Markus,
I think I found a solution: ecoDMS ldap setting allows to configure as LDAP or as AD. Choosing LDAP with CN as the UID works. It solves the problem, but I still do not understand why sAMAccountName gives a result which can not be used.
In fact sAMAccountName ist an old legacy support while starting from Windows 2000 UserPrincipleName is “item of choice”.
I am happy - it works and I was able to take over the database with exactly the same system rights and assignments.
Best regards
Thorsten
