Sources allow you to connect authentik to an existing user directory. They can also be used for social logins, using external providers such as Facebook, Twitter, etc.
- Server URI: URI to your LDAP server/Domain Controller.
- Bind CN: CN of the bind user. This can also be a UPN in the format of `user@domain.tld`.
- Bind password: Password used during the bind process.
- Enable StartTLS: Enables StartTLS functionality. To use LDAPS instead, use port `636`.
- Base DN: Base DN used for all LDAP queries.
- Addition User DN: Prepended to the base DN for user queries.
- Addition Group DN: Prepended to the base DN for group queries.
- User object filter: Consider objects matching this filter to be users.
- Group object filter: Consider objects matching this filter to be groups.
- User group membership field: This field contains the user's group memberships.
- Object uniqueness field: This field contains a unique identifier.
- Sync groups: Enable/disable group synchronization. Groups are synced in the background every 5 minutes.
- Sync parent group: Optionally set this group as the parent group for all synced groups. An example use case of this would be to import Active Directory groups under a root `imported-from-ad` group.
- Property mappings: Define which LDAP properties map to which authentik properties. The default set of property mappings is generated for Active Directory. See also [LDAP Property Mappings](../../../docs/property-mappings/index#ldap-property-mapping)
