8.3. Authentication Server

You can find the Authentication Server Settings at Authentication → Auth. Server.

On the Authentication Server screen you can quick edit some settings like activating/deactivating and deleting authentication servers.

Authentication Server Creation

Each server can have a name and can be enabled individually. You can choose either LDAP or RADIUS as type.

After creating the Authentication Server you still need to create a user with the same username in User. A password has to be supplied as well which might be random. The user will only be authenticated against the chosen Authentication Server though.
