Setting up LDAP user

Hi *,

I just set up a new 11.3 (32 bit) and try to insert a user for LDAP authentication.

Every handbook I read so far said “Enter the Plug-Ins tab, select the LDAP plug-in, and click Launch to configure additional LDAP attributes assigned to the new user”.

However, going into this very tab, all I see is the Quota Plugin. No LDAP Plugin available for me. It’s just not there…

What did I do before?
LDAP server configured and running.
LDAP client configured and running.
Set up local user.

How can I continue? Where will I have to look?

Thank you all! Kind regards,
