We have two documentation pieces for LDAP authentication:

* LDAP auth source: [https://www.openproject.org/docs/system-admin-guide/authentication/ldap-authentication/](https://www.openproject.org/docs/system-admin-guide/authentication/ldap-authentication/)
* LDAP group synchronization: [https://www.openproject.org/docs/system-admin-guide/authentication/ldap-authentication/ldap-group-synchronization](https://www.openproject.org/docs/system-admin-guide/authentication/ldap-authentication/ldap-group-synchronization)
