samba - Mar 2013 - Samba4 issue: roaming profile mismatch betweens W2k/XP machines due to enabled o

Samba 4.0.4 installed, provisioned by classicupgrade, running on Debian Squeeze:
--------------------------------------------------------------------------------
The issue is, that changes to the roaming profile is not transferred after log
ins/outs between Win2K and XP machine. In example: I log into the W2k machine
with my testuser and create a "testdir1" and "testdir2" on
the Desktop. I logoff again. I check with "ls -l" if these directories
was created on samba4 side at the file system (profiles share path). The test
directories were created and the permissions + acls looks fine. Now I logon with
this testuser at winXP machine. I can see "testdir1" +
"testdir2" on the desktop. Now I delete "testdir1" and
create a new dir called "fromxphost". So I see on the XP machine two
dirs, called "testdir2" + "fromxphost". I logoff from the
XPhost and log into the w2k machine again. Here is the issue --> I see three
directories, called "testdir1", "testdir2" and
"fromxphost". When I logoff now again, these 3 directories will of
course saved exactly like this onto the roaming profile. When the user logs into
XP machine afterwards, he also will see these 3 directories. I have tested
various user account and w2k/xp hosts. When I add/delete directories on this way
to the w2k host logged on, no problem occurs. The user sees the updated
directories. The problem occurs when the user switches from W2K --to---> XP
host, or vice-versa.

I think I have found out the reason of my problem with w2k clients and roaming
profile mismatch --> samba4 uses offline caching which I cannot explain why
so? In samba3 there was an option in smb.conf called "csc policy" or
something like that. But smb.conf in samba4 doesn't seem to exist. I have
realized that a Windows XP client in my samba4 domain writes warning to the
event log that offline caching on the roaming profile was detected !
Unfortunately I see no way to disable that on samba4 server. Exact the same
issue was mentioned by another user in February on the samba list here:

http://samba.2283325.n4.nabble.com/Offline-Caching-td4357156.html

With WinXP and Win7 there seems no problem as the content of the roaming profile
seems to be saved/loaded correctly. Didnt realize any mismatch issues with
WinXP/Win7 clients before. But on W2k clients it does NOT :( thats really a big
issue in my case, cause we still have about 15-20 W2k clients in prod.
environment. At luck I am not migrated yet to Samba4 on prod.env. cause I am
still testing on my isolated test environment where I test with various Win2k,
WinXP and Win7 clients. Under this circumstances I **CANNOT** migrate my samba3
domain to the new samba4 domain, as all my W2k clients would show this issue.
Any information on developer side regarding this offline caching mechanism on
samba4 ? any help, hint, info is really appreciated.

Hi Lucas,

This is normal. when a user logs in, everything from user profile is copied
to c:\docs and settings\<username> and when they log out everything is
copied back, but nothing is deleted. As a result, you get all manner of
junk building up in your profile, its not easy to delete and logins just
get slower and slower as all this is copied about.

I get round this by redirecting desktop to either a read only share or to a
subdirectory of networked my docs folder. Also I use preexec scripts to
manage user profile.

Hope that helps

Jim
