[CentOS] Domain Logout, then domain login again, profile corrupt -> replaced by TEMP profile

Hi

I have had this problem for a while, but waited to post this until I upgraded to
see whether the upgrade would fix it.
I upgraded samba to the 4.2.X stream from 3.6.X stream, but it happens on both,
3.6.X and 4.2.10.

Whenever someone logs out, then in again the profile gets corrupted and a new
TEMP profile is created (the dreadful "creating new desktop"). Now I
do not know where this problem is - the desktop or the server.
It also happens if you wait 1/2 hour or so, never tried it longer.

I can quickly fix this by:

 - tell the user to log out
 - rsync -avHAX the profile with yesterdays profile
 - tell the user to log in again

Now if I log out on my workstation, then on the server I do a "smb
reload", then log in again this problem does not happen.

This morning a person logged out of his workstation, went over to the bigscreen
in one of our training rooms and logged in there, then logged out, went over to
his machine but got the dreadful "preparing desktop" on login ....

Anybody got any idea?

thanks
Jobst
