roaming profiles not updating

[johnny t chang]

*** THE PROBLEM

i'm running 2.1.0 prealpha ... Linux server w/ NT clients ... for
some reason, when users log into the domain from workstations, their
profiles are not saved back to the server ... AND/OR their profiles
aren't being downloaded from the server.



*** SOME OBSERVATIONS

i set up a brand new client today.  when i log in, then log out, then
log in as administrator on the client ... i can see from looking at
C:\Winnt\Profiles\johnny (there is no local user named johnny) that the
server profile has been downloaded.

then, if i log back in on the domain account, and change a setting --
say the wallpaper -- then log back out ... then i log in as local
administrator ... i notice that the local NTUSER.DAT file for johnny
still has the old time (sometime in December) ... but if i open that
registry hive with regedt32.exe, the wallpaper setting has been
correctly changed.

now, if i look at the server NTUSER.DAT, the wallpaper setting has not
been correctly changed.

the next thing i did was to manually modify the loaded hive, and then
unload it ... this does then change the "Modified" time to today.  when
i then try to log into the domain, i get a dialog that says the locally
cached profile is newer (which is correct), and whether i want to use it
... i say "Yes," but the wallpaper is not the one listed in the local
NTUSER.dat ... AND when i log out, the server version doesn't get
updated.

any ideas?

thanks!
