Also Ticket#2016082621000083 because of the environment this may gain severity quickly. Since the behaviour may happen generally in @school environments with a similar setting (bad connection between school sites and the master) and the UMC is a major administration tool in these environments I bumped the Bug-type to "5". Do we have any information that indicate the root cause of the problem? (In reply to Sönke Schwardt-Krummrich from comment #3) > Do we have any information that indicate the root cause of the problem? What do you mean with root cause? 1. Why the DC Master is not available or 2. Why this is so slow 2. → PAM (the timeouts in each module of the pam stack) Created attachment 8139 [details]
patch
Ahh, no! I checked the whole UMC-Server code and got the problem. There is a ldap connection to the master - which is obviously wrong. Patch attached.
