LDAP configuration

Connect LDAP/Active Directory – authentication, synchronization, filters and attribute mapping.

On this page

Menu Administration → LDAP configuration. An LDAP (e.g. Microsoft Active Directory) is a hierarchical directory service for central management of resources such as users. Nuclos uses LDAP for authentication and a simple synchronization (LDAP → Nuclos); authorization remains in Nuclos.

Authentication

Users found via the authentication filter are checked against the LDAP – the Nuclos password is ignored.
Users not found cannot log in (exception: super users – the Nuclos password is also tried for them if the LDAP is unavailable).
The test authentication button verifies a user/password combination.

Users must be created manually in Nuclos with the same user name and assigned to a group with the system start right. Synchronization neither creates nor deletes users.

Synchronization

With an active LDAP configuration a synchronization icon appears in the user detail view. It copies first name, last name and e-mail from the configured LDAP attributes.
