Hello together 
I have a setup where the users don’t have local profiles, instead they get their home directory mounted by the login server (with mkhomedir and pam_mount).
Home directories are on a CIFS share, as far as i can see the permissions are pretty good.
Local users get their desktop as expected, but some users (2 from 10) authenticated by the login server have a strange desktop.
When logged in, desktop rebuilds, icons are exact positioned, but then the bars begin to jump and finally they disappear.
Having a look at .xsession-errors seems to be a nightmare 
I am a bit confused, since some errors say: permission denied.
Especially “g_rename() failed: Permission denied” seem to be the reason…
How can this happen?
When i ssh into these machines, they have the same permissions like the others.
Setup was done scripted, so i can be 100% sure there is no user interaction which has caused this issue.
When pressing Alt+F1, the top and bottom bars scroll in, and a second later they are gone 
Any help appreciated
