Description Michael Grandjean univentionstaff 2017-10-24 12:34:38 CEST
If the UCS Master in a UCS@school multiserver environment is not a Samba AD DC, the "Well Known SIDs" check on the school servers will always complain about missing accounts for "KRBTGT" and "Guest":

> Kein Nutzer oder keine Gruppe mit SID S-1-5-21-1858433575-2913521688-961427091-502 gefunden, 'KRBTGT' war erwartet. 
> Kein Nutzer oder keine Gruppe mit SID S-1-5-21-1858433575-2913521688-961427091-501 gefunden, 'Guest' war erwartet.

AFAICS this is because the check only searches for those accounts in OpenLDAP, but in this case they only exist on the Samba AD side on the UCS@school Slave.

Error occurred as well under DcSlave (UCS 4.2-3) when setting up scenario 3 from http://docs.software-univention.de/ucsschool-szenarien-4.2-de.html#scenario-3
Comment 2 Ingo Steuwer univentionstaff 2020-07-03 20:55:03 CEST
This issue has been filed against UCS 4.2.

UCS 4.2 is out of maintenance and many UCS components have changed in later releases. Thus, this issue is now being closed.

If this issue still occurs in newer UCS versions, please use "Clone this bug" or reopen it and update the UCS version. In this case please provide detailed information on how this issue is affecting you.

Still a problem. Noticed during preparation for the 5.0v2 school release.
