Problem: Users Can Not Logon to Windows Terminal Server

Problem

Some users get denied when trying to use Windows terminal servers.

Solution

For some reason some of the users had additional attributes set in their account properties:
userParameters

Removing these unneeded attributes fixed the issue and the users could use terminal services.

root@ucs:~# ldapmodify -D "$( ucr get ldap/hostdn )" -y /etc/machine.secret <<%EOR
<USERDN>
changetype: modify
delete: userParameters
%EOR

To find all affected users you can search for

univention-ldapsearch "(userParameters=*)" dn userParameters
Mastodon
