Univention Bugzilla – Bug 36588
Speed up user login with local profile
Last modified: 2019-02-05 21:20:40 CET
A customer reported for paedML Linux that the first login of a user takes very long. For normal users this is okay, but for exam users speed is important. Idea: Instead of using a server based profile exam users are forced to local profiles. It's not clear if this local profile can be exploited by preparing files in it. I'd assume that if a user writes two exam the two exam-<username> users have different SID an can access data from one another.
Alternatively a customer which from the summit was to create the exam already in the night/day before (with an automatic login so that the profiles get created) so that the user accounts exists then already.

The time for creating new profiles is heavily influenced by installed software. > Idea: Instead of using a server based profile exam users are forced to local > profiles. AFAIK the server side profile is copied to the windows client upon login and copied back to server upon logout. If no profile exists, a new profile is created. So currently I do not assume that there is a performance gain if a local profile is used.
Could this be related to Bug 37854?
There is a Customer ID set so I set the flag "School Customer affected".
