Hello @isol ,
from what I’ve heard from our support I would not recommend to use Samba 4 LDAP for user groups larger than 100 users. The Univention App used the internal OpenLDAP from the start, so in the sense of “don’t fix what isn’t broken” it never switched over to the Samba 4 auth.
@isol said in Kopano Auth against Univention:
if the customer later migrates to a real Windows DC I assume it is less work on the kopano side !?
changing the auth source almost always comes with different unique user keys, so if i don’t think it matters which kind of ldap implementation you are running now, from the Kopano side of things both will be equally intensive.
Maybe except for the fact that it may be a bit easier to migrate tree data into an ads from samba, than it is from openldap.
