# Each policy is configured under a separate namespace, e.g.
#    dbms.ssl.policy.<policyname>.*
#
# The example settings below are for a new policy named 'default'.

# The base directory for cryptographic objects. Each policy will by
# default look for its associated objects (keys, certificates, ...)
# under the base directory.
#
# Every such setting can be overridden using a full path to
# the respective object, but every policy will by default look
# for cryptographic objects in its base location.
#
# Mandatory setting

#dbms.ssl.policy.default.base_directory=certificates/default

# Allows the generation of a fresh private key and a self-signed
# certificate if none are found in the expected locations. It is
# recommended to turn this off again after keys have been generated.
#
# Keys should in general be generated and distributed offline
# by a trusted certificate authority (CA) and not by utilizing
# this mode.

#dbms.ssl.policy.default.allow_key_generation=false

# Enabling this makes it so that this policy ignores the contents
# of the trusted_dir and simply resorts to trusting everything.
#
# Use of this mode is discouraged. It would offer encryption but no security.

#dbms.ssl.policy.default.trust_all=false

# The private key for the default SSL policy. By default a file
# named private.key is expected under the base directory of the policy.
# It is mandatory that a key can be found or generated.

#dbms.ssl.policy.default.private_key=

# The private key for the default SSL policy. By default a file
# named public.crt is expected under the base directory of the policy.
# It is mandatory that a certificate can be found or generated.

#dbms.ssl.policy.default.public_certificate=

# The certificates of trusted parties. By default a directory named
# 'trusted' is expected under the base directory of the policy. It is
# mandatory to create the directory so that it exists, because it cannot
# be auto-created (for security purposes).
#
# To enforce client authentication client_auth must be set to 'require'!

#dbms.ssl.policy.default.trusted_dir=

# Certificate Revocation Lists (CRLs). By default a directory named
# 'revoked' is expected under the base directory of the policy. It is
# mandatory to create the directory so that it exists, because it cannot
# be auto-created (for security purposes).

#dbms.ssl.policy.default.revoked_dir=

# Client authentication setting. Values: none, optional, require
# The default is to require client authentication.

# should be kept at the default of require and trusted certificates
# must be installed in the trusted_dir.

#dbms.ssl.policy.default.client_auth=require

# It is possible to verify the hostname that the client uses
# to connect to the remote server. In order for this to work, the server public

# Will select all available servers as the default policy, which is the
# policy used when the client does not specify a policy preference. The
# default configuration for the default policy is all().
#causal_clustering.load_balancing.config.server_policies.default=all()

# Will select servers in groups 'group1' or 'group2' under the default policy.
#causal_clustering.load_balancing.config.server_policies.default=groups(group1,group2)

# Slightly more advanced example:
# Will select servers in 'group1', 'group2' or 'group3', but only if there are at least 2.
# This policy will be exposed under the name of 'mypolicy'.
#causal_clustering.load_balancing.config.server_policies.mypolicy=groups(group1,group2,group3) -> min(2)

# Below will create an even more advanced policy named 'regionA' consisting of several rules
# yielding the following behaviour:
#
#            select servers in regionA, if at least 2 are available
# otherwise: select servers in regionA and regionB, if at least 2 are available
# otherwise: select all servers
#
# The intention is to create a policy for a particular region which prefers
# a certain set of local servers, but which will fallback to other regions
# or all available servers as required.
#
# N.B: The following configuration uses the line-continuation character \
#      which allows you to construct an easily readable rule set spanning
#      several lines.
#
#causal_clustering.load_balancing.config.server_policies.policyA=\
#groups(regionA) -> min(2);\

#================================================
# LDAP Auth Provider Configuration
#================================================

# URL of LDAP server to use for authentication and authorization.
# The format of the setting is `<protocol>://<hostname>:<port>`, where hostname is the only required field.
# The supported values for protocol are `ldap` (default) and `ldaps`.
# The default port for `ldap` is 389 and for `ldaps` 636.
# For example: `ldaps://ldap.example.com:10389`.
#
# NOTE: You may want to consider using STARTTLS (`dbms.security.ldap.use_starttls`) instead of LDAPS
# for secure connections, in which case the correct protocol is `ldap`.
#dbms.security.ldap.host=localhost

# Use secure communication with the LDAP server using opportunistic TLS.
# First an initial insecure connection will be made with the LDAP server, and then a STARTTLS command
# will be issued to negotiate an upgrade of the connection to TLS before initiating authentication.
#dbms.security.ldap.use_starttls=false

# The LDAP referral behavior when creating a connection. This is one of `follow`, `ignore` or `throw`.
# `follow` automatically follows any referrals
# `ignore` ignores any referrals
# `throw` throws an exception, which will lead to authentication failure
#dbms.security.ldap.referral=follow

# The timeout for establishing an LDAP connection. If a connection with the LDAP server cannot be
# established within the given time the attempt is aborted.
# A value of 0 means to use the network protocol's (i.e., TCP's) timeout value.
#dbms.security.ldap.connection_timeout=30s

# The timeout for an LDAP read request (i.e. search). If the LDAP server does not respond within
# the given time the request will be aborted. A value of 0 means wait for a response indefinitely.
#dbms.security.ldap.read_timeout=30s

#----------------------------------
# LDAP Authentication Configuration
#----------------------------------

# LDAP authentication mechanism. This is one of `simple` or a SASL mechanism supported by JNDI,
# for example `DIGEST-MD5`. `simple` is basic username
# and password authentication and SASL is used for more advanced mechanisms. See RFC 2251 LDAPv3
# documentation for more details.
#dbms.security.ldap.authentication.mechanism=simple

# LDAP user DN template. An LDAP object is referenced by its distinguished name (DN), and a user DN is
# an LDAP fully-qualified unique user identifier. This setting is used to generate an LDAP DN that
# conforms with the LDAP directory's schema from the user principal that is submitted with the
# authentication token when logging in.
# The special token {0} is a placeholder where the user principal will be substituted into the DN string.
#dbms.security.ldap.authentication.user_dn_template=uid={0},ou=users,dc=example,dc=com

# Determines if the result of authentication via the LDAP server should be cached or not.
# Caching is used to limit the number of LDAP requests that have to be made over the network
# for users that have already been authenticated successfully. A user can be authenticated against
# an existing cache entry (instead of via an LDAP server) as long as it is alive
# (see `dbms.security.auth_cache_ttl`).
# An important consequence of setting this to `true` is that
# Neo4j then needs to cache a hashed version of the credentials in order to perform credentials
# matching. This hashing is done using a cryptographic hash function together with a random salt.
# Preferably a conscious decision should be made if this method is considered acceptable by
# the security standards of the organization in which this Neo4j instance is deployed.
#dbms.security.ldap.authentication.cache_enabled=true

#----------------------------------
# LDAP Authorization Configuration
#----------------------------------
# Authorization is performed by searching the directory for the groups that
# the user is a member of, and then map those groups to Neo4j roles.

# Perform LDAP search for authorization info using a system account instead of the user's own account.
#
# If this is set to `false` (default), the search for group membership will be performed
# directly after authentication using the LDAP context bound with the user's own account.
# The mapped roles will be cached for the duration of `dbms.security.auth_cache_ttl`,
# and then expire, requiring re-authentication. To avoid frequently having to re-authenticate
# sessions you may want to set a relatively long auth cache expiration time together with this option.
# NOTE: This option will only work if the users are permitted to search for their
# own group membership attributes in the directory.
#
# If this is set to `true`, the search will be performed using a special system account user
# with read access to all the users in the directory.
# You need to specify the username and password using the settings
# `dbms.security.ldap.authorization.system_username` and
# `dbms.security.ldap.authorization.system_password` with this option.
# Note that this account only needs read access to the relevant parts of the LDAP directory
# and does not need to have access rights to Neo4j, or any other systems.
#dbms.security.ldap.authorization.use_system_account=false

# An LDAP system account username to use for authorization searches when
# `dbms.security.ldap.authorization.use_system_account` is `true`.
# Note that the `dbms.security.ldap.authentication.user_dn_template` will not be applied to this username,
# so you may have to specify a full DN.
#dbms.security.ldap.authorization.system_username=

# An LDAP system account password to use for authorization searches when

#================================================
# LDAP Auth Provider Configuration
#================================================

# URL of LDAP server to use for authentication and authorization.
# The format of the setting is `<protocol>://<hostname>:<port>`, where hostname is the only required field.
# The supported values for protocol are `ldap` (default) and `ldaps`.
# The default port for `ldap` is 389 and for `ldaps` 636.
# For example: `ldaps://ldap.example.com:10389`.
#
# NOTE: You may want to consider using STARTTLS (`dbms.security.ldap.use_starttls`) instead of LDAPS
# for secure connections, in which case the correct protocol is `ldap`.
#dbms.security.ldap.host=localhost

# Use secure communication with the LDAP server using opportunistic TLS.
# First an initial insecure connection will be made with the LDAP server, and then a STARTTLS command
# will be issued to negotiate an upgrade of the connection to TLS before initiating authentication.
#dbms.security.ldap.use_starttls=false

# The LDAP referral behavior when creating a connection. This is one of `follow`, `ignore` or `throw`.
# `follow` automatically follows any referrals
# `ignore` ignores any referrals
# `throw` throws an exception, which will lead to authentication failure
#dbms.security.ldap.referral=follow

# The timeout for establishing an LDAP connection. If a connection with the LDAP server cannot be
# established within the given time the attempt is aborted.
# A value of 0 means to use the network protocol's (i.e., TCP's) timeout value.
#dbms.security.ldap.connection_timeout=30s

# The timeout for an LDAP read request (i.e. search). If the LDAP server does not respond within
# the given time the request will be aborted. A value of 0 means wait for a response indefinitely.
#dbms.security.ldap.read_timeout=30s

#----------------------------------
# LDAP Authentication Configuration
#----------------------------------

# LDAP authentication mechanism. This is one of `simple` or a SASL mechanism supported by JNDI,
# for example `DIGEST-MD5`. `simple` is basic username
# and password authentication and SASL is used for more advanced mechanisms. See RFC 2251 LDAPv3
# documentation for more details.
#dbms.security.ldap.authentication.mechanism=simple

# LDAP user DN template. An LDAP object is referenced by its distinguished name (DN), and a user DN is
# an LDAP fully-qualified unique user identifier. This setting is used to generate an LDAP DN that
# conforms with the LDAP directory's schema from the user principal that is submitted with the
# authentication token when logging in.
# The special token {0} is a placeholder where the user principal will be substituted into the DN string.
#dbms.security.ldap.authentication.user_dn_template=uid={0},ou=users,dc=example,dc=com

# Determines if the result of authentication via the LDAP server should be cached or not.
# Caching is used to limit the number of LDAP requests that have to be made over the network
# for users that have already been authenticated successfully. A user can be authenticated against
# an existing cache entry (instead of via an LDAP server) as long as it is alive
# (see `dbms.security.auth_cache_ttl`).
# An important consequence of setting this to `true` is that
# Neo4j then needs to cache a hashed version of the credentials in order to perform credentials
# matching. This hashing is done using a cryptographic hash function together with a random salt.
# Preferably a conscious decision should be made if this method is considered acceptable by
# the security standards of the organization in which this Neo4j instance is deployed.
#dbms.security.ldap.authentication.cache_enabled=true

#----------------------------------
# LDAP Authorization Configuration
#----------------------------------
# Authorization is performed by searching the directory for the groups that
# the user is a member of, and then map those groups to Neo4j roles.

# Perform LDAP search for authorization info using a system account instead of the user's own account.
#
# If this is set to `false` (default), the search for group membership will be performed
# directly after authentication using the LDAP context bound with the user's own account.
# The mapped roles will be cached for the duration of `dbms.security.auth_cache_ttl`,
# and then expire, requiring re-authentication. To avoid frequently having to re-authenticate
# sessions you may want to set a relatively long auth cache expiration time together with this option.
# NOTE: This option will only work if the users are permitted to search for their
# own group membership attributes in the directory.
#
# If this is set to `true`, the search will be performed using a special system account user
# with read access to all the users in the directory.
# You need to specify the username and password using the settings
# `dbms.security.ldap.authorization.system_username` and
# `dbms.security.ldap.authorization.system_password` with this option.
# Note that this account only needs read access to the relevant parts of the LDAP directory
# and does not need to have access rights to Neo4j, or any other systems.
#dbms.security.ldap.authorization.use_system_account=false

# An LDAP system account username to use for authorization searches when
# `dbms.security.ldap.authorization.use_system_account` is `true`.
# Note that the `dbms.security.ldap.authentication.user_dn_template` will not be applied to this username,
# so you may have to specify a full DN.
#dbms.security.ldap.authorization.system_username=

# An LDAP system account password to use for authorization searches when
# `dbms.security.ldap.authorization.use_system_account` is `true`.
#dbms.security.ldap.authorization.system_password=

# The name of the base object or named context to search for user objects when LDAP authorization is enabled.
# A common case is that this matches the last part of `dbms.security.ldap.authentication.user_dn_template`.
#dbms.security.ldap.authorization.user_search_base=ou=users,dc=example,dc=com

# The LDAP search filter to search for a user principal when LDAP authorization is
# enabled. The filter should contain the placeholder token {0} which will be substituted for the
# user principal.
#dbms.security.ldap.authorization.user_search_filter=(&(objectClass=*)(uid={0}))

# A list of attribute names on a user object that contains groups to be used for mapping to roles
# when LDAP authorization is enabled.
#dbms.security.ldap.authorization.group_membership_attributes=memberOf

# An authorization mapping from LDAP group names to Neo4j role names.
# The map should be formatted as a semicolon separated list of key-value pairs, where the
# key is the LDAP group name and the value is a comma separated list of corresponding role names.
# For example: group1=role1;group2=role2;group3=role3,role4,role5
#
# You could also use whitespaces and quotes around group names to make this mapping more readable,
# for example: dbms.security.ldap.authorization.group_to_role_mapping=\

# The maximum capacity for authentication and authorization caches (respectively).
#dbms.security.auth_cache_max_capacity=10000

# Set to log successful authentication events to the security log.

# could be useful if you find that the successful events spam the logs too much,
# and you do not require full auditing capability.
#dbms.security.log_successful_authentication=true

#================================================
# LDAP Auth Provider Configuration
#================================================

# URL of LDAP server to use for authentication and authorization.
# The format of the setting is `<protocol>://<hostname>:<port>`, where hostname is the only required field.
# The supported values for protocol are `ldap` (default) and `ldaps`.
# The default port for `ldap` is 389 and for `ldaps` 636.
# For example: `ldaps://ldap.example.com:10389`.
#
# NOTE: You may want to consider using STARTTLS (`dbms.security.ldap.use_starttls`) instead of LDAPS
# for secure connections, in which case the correct protocol is `ldap`.
#dbms.security.ldap.host=localhost

# Use secure communication with the LDAP server using opportunistic TLS.
# First an initial insecure connection will be made with the LDAP server, and then a STARTTLS command
# will be issued to negotiate an upgrade of the connection to TLS before initiating authentication.
#dbms.security.ldap.use_starttls=false

# The LDAP referral behavior when creating a connection. This is one of `follow`, `ignore` or `throw`.
# `follow` automatically follows any referrals
# `ignore` ignores any referrals
# `throw` throws an exception, which will lead to authentication failure
#dbms.security.ldap.referral=follow

# The timeout for establishing an LDAP connection. If a connection with the LDAP server cannot be
# established within the given time the attempt is aborted.
# A value of 0 means to use the network protocol's (i.e., TCP's) timeout value.
#dbms.security.ldap.connection_timeout=30s

# The timeout for an LDAP read request (i.e. search). If the LDAP server does not respond within
# the given time the request will be aborted. A value of 0 means wait for a response indefinitely.
#dbms.security.ldap.read_timeout=30s

#----------------------------------
# LDAP Authentication Configuration
#----------------------------------

# LDAP authentication mechanism. This is one of `simple` or a SASL mechanism supported by JNDI,
# for example `DIGEST-MD5`. `simple` is basic username
# and password authentication and SASL is used for more advanced mechanisms. See RFC 2251 LDAPv3
# documentation for more details.
#dbms.security.ldap.authentication.mechanism=simple

# LDAP user DN template. An LDAP object is referenced by its distinguished name (DN), and a user DN is
# an LDAP fully-qualified unique user identifier. This setting is used to generate an LDAP DN that
# conforms with the LDAP directory's schema from the user principal that is submitted with the
# authentication token when logging in.
# The special token {0} is a placeholder where the user principal will be substituted into the DN string.
#dbms.security.ldap.authentication.user_dn_template=uid={0},ou=users,dc=example,dc=com

# Determines if the result of authentication via the LDAP server should be cached or not.
# Caching is used to limit the number of LDAP requests that have to be made over the network
# for users that have already been authenticated successfully. A user can be authenticated against
# an existing cache entry (instead of via an LDAP server) as long as it is alive
# (see `dbms.security.auth_cache_ttl`).
# An important consequence of setting this to `true` is that
# Neo4j then needs to cache a hashed version of the credentials in order to perform credentials
# matching. This hashing is done using a cryptographic hash function together with a random salt.
# Preferably a conscious decision should be made if this method is considered acceptable by
# the security standards of the organization in which this Neo4j instance is deployed.
#dbms.security.ldap.authentication.cache_enabled=true

#----------------------------------
# LDAP Authorization Configuration
#----------------------------------
# Authorization is performed by searching the directory for the groups that
# the user is a member of, and then map those groups to Neo4j roles.

# Perform LDAP search for authorization info using a system account instead of the user's own account.
#
# If this is set to `false` (default), the search for group membership will be performed
# directly after authentication using the LDAP context bound with the user's own account.
# The mapped roles will be cached for the duration of `dbms.security.auth_cache_ttl`,
# and then expire, requiring re-authentication. To avoid frequently having to re-authenticate
# sessions you may want to set a relatively long auth cache expiration time together with this option.
# NOTE: This option will only work if the users are permitted to search for their
# own group membership attributes in the directory.
#
# If this is set to `true`, the search will be performed using a special system account user
# with read access to all the users in the directory.
# You need to specify the username and password using the settings
# `dbms.security.ldap.authorization.system_username` and
# `dbms.security.ldap.authorization.system_password` with this option.
# Note that this account only needs read access to the relevant parts of the LDAP directory
# and does not need to have access rights to Neo4j, or any other systems.
#dbms.security.ldap.authorization.use_system_account=false

# An LDAP system account username to use for authorization searches when
# `dbms.security.ldap.authorization.use_system_account` is `true`.
# Note that the `dbms.security.ldap.authentication.user_dn_template` will not be applied to this username,
# so you may have to specify a full DN.
#dbms.security.ldap.authorization.system_username=

# An LDAP system account password to use for authorization searches when
# `dbms.security.ldap.authorization.use_system_account` is `true`.
#dbms.security.ldap.authorization.system_password=

# The name of the base object or named context to search for user objects when LDAP authorization is enabled.
# A common case is that this matches the last part of `dbms.security.ldap.authentication.user_dn_template`.
#dbms.security.ldap.authorization.user_search_base=ou=users,dc=example,dc=com

# The LDAP search filter to search for a user principal when LDAP authorization is
# enabled. The filter should contain the placeholder token {0} which will be substituted for the
# user principal.
#dbms.security.ldap.authorization.user_search_filter=(&(objectClass=*)(uid={0}))

# A list of attribute names on a user object that contains groups to be used for mapping to roles
# when LDAP authorization is enabled.
#dbms.security.ldap.authorization.group_membership_attributes=memberOf

# An authorization mapping from LDAP group names to Neo4j role names.
# The map should be formatted as a semicolon separated list of key-value pairs, where the
# key is the LDAP group name and the value is a comma separated list of corresponding role names.
# For example: group1=role1;group2=role2;group3=role3,role4,role5
#
# You could also use whitespaces and quotes around group names to make this mapping more readable,
# for example: dbms.security.ldap.authorization.group_to_role_mapping=\
#          "cn=Neo4j Read Only,cn=users,dc=example,dc=com"      = reader;    \
#          "cn=Neo4j Read-Write,cn=users,dc=example,dc=com"     = publisher; \
#          "cn=Neo4j Schema Manager,cn=users,dc=example,dc=com" = architect; \
