There is nothing special about this domain, other than the fact that it must exist to order to maintain support for your v2 clients.

domain_configurations_from_database = False (Boolean) Extract the domain specific configuration options from the resource backend where they have been stored with the domain data.

use_tls = False (Boolean) Enable TLS for communicating with LDAP servers.
user = None (String) User BindDN to query the LDAP server.

user_enabled_default = True (String) Default value to enable users. This should match an appropriate int value if the LDAP server uses non-boolean (bitmask) values to indicate if a user is enabled or disabled. If this is not set to “True” the typical value is “512”. This is typically used when “user_enabled_attribute = userAccountControl”.
user_enabled_emulation = False (Boolean) If true, Keystone uses an alternative method to determine if a user is enabled or not by checking if they are a member of the “user_enabled_emulation_dn” group.
user_enabled_emulation_dn = None (String) DN of the group entry to hold enabled users when using enabled emulation.
user_enabled_emulation_use_group_config = False (Boolean) Use the “group_member_attribute” and “group_objectclass” settings to determine membership in the emulated enabled group.
user_enabled_invert = False (Boolean) Invert the meaning of the boolean enabled values. Some LDAP servers use a boolean lock attribute where “true” means an account is disabled.

Description of mapping configuration options
Configuration option = Default value Description
[identity_mapping]  
backward_compatible_ids = True (Boolean) The format of user and group IDs changed in Juno for backends that do not generate UUIDs (e.g. LDAP), with keystone providing a hash mapping to the underlying attribute in LDAP. By default this mapping is disabled, which ensures that existing IDs will not change. Even when the mapping is enabled by using domain specific drivers, any users and groups from the default domain being handled by LDAP will still not be mapped to ensure their IDs remain backward compatible. Setting this value to False will enable the mapping for even the default LDAP driver. It is only safe to do this if you do not already have assignments for users and groups from the default LDAP domain, and it is acceptable for Keystone to provide the different IDs to clients than it did previously. Typically this means that the only time you can set this value to False is when configuring a fresh installation.
driver = sql (String) Entrypoint for the identity mapping backend driver in the keystone.identity.id_mapping namespace.

Description of security configuration options
Configuration option = Default value Description
[DEFAULT]  
crypt_strength = 10000 (Integer) The value passed as the keyword “rounds” to passlib’s encrypt method. This option represents a trade off between security and performance. Higher values lead to slower performance, but higher security. Changing this option will only affect newly created passwords as existing password hashes already have a fixed number of rounds applied, so it is safe to tune this option in a running cluster.

hash_algorithm = md5 (String) DEPRECATED: The hash algorithm to use for PKI tokens. This can be set to any algorithm that hashlib supports. WARNING: Before changing this value, the auth_token middleware must be configured with the hash_algorithms, otherwise token revocation will not be processed correctly. PKI token support has been deprecated in the M release and will be removed in the O release. Fernet or UUID tokens are recommended.
infer_roles = True (Boolean) Add roles to token that are not explicitly added, but that are linked implicitly to other roles.
provider = uuid (String) Controls the token construction, validation, and revocation operations. Entrypoint in the keystone.token.provider namespace. Core providers are [fernet|pkiz|pki|uuid].
revoke_by_id = True (Boolean) Revoke token by token identifier. Setting revoke_by_id to true enables various forms of enumerating tokens, e.g. list tokens for user. These enumerations are processed to determine the list of tokens to revoke. Only disable if you are switching to using the Revoke extension with a backend other than KVS, which stores events in memory.
