Description Sönke Schwardt-Krummrich univentionstaff 2018-03-03 22:12:07 CET
UCS master+slave has been updated from 4.2-3 to 4.3-0. Afterwards the logfile management-console-web-server.log is spammed with the following logfiles each 30 seconds for each UMC session.

==> management-console-web-server.log <==

Comment 1 Jannik Ahlers univentionstaff 2018-03-16 13:26:22 CET
The log is generated by the session-info query which tries to get the user's group using the memberof attribute. This is of course not possible if the memberof overlay is deactivated.

But there is another side effect of this if the memberof overlay is deactivated: 
The new function to change portal object's visibility depending on a user's group membership uses the group membership information provided in the session-info query. This behaviour is broken due to session-info returning 'null' when the  memberof-overlay is deactivated.
Comment 2 Jannik Ahlers univentionstaff 2018-05-07 17:09:17 CEST
I simply set the loglevel to info to reduce spamming.

Successful build

Okay, better.

Yes, this is documented in the manual.
