[Samba] Difficulty w/Offline Files and Samba 3.0.25

Good morning,

I have a working Offline Files setup w/Samba 3.0.24 (FreeBSD 6.2 host OS)
and a Win XP SP2 client.  Upon updating to Samba 3.0.25, the XP client's
offline cache would show (as viewed via the Offline Files Folder) that
synced files are write-only ('User W' in the Access column).  When
offline, theses files appeared to be available via Explorer and double
clicking would launch the appropriate program, but would then generate a
file not found error.  Reverting to Samba 3.0.24 and resyncing has
corrected the problem ('User R/W' in the Access column and proper access
restored when offline).

My smb.conf is attached.  Apart from the 'map acl inherit' parameter,
which I added when upgrading to 3.0.25 at the suggestion of WHATSNEW.txt,
this configuration file has not been changed in several months.  Any
suggestions as to what the cause of this problem could be?  Are any of
the recent changes in 3.0.25a likely applicable to this problem?

Thanks for the help!

David

[Samba] Difficulty w/Offline Files and Samba 3.0.25

I filed a bug report about this exact issue yesterday.  Everything you
are describing aligns 100% with what I'm experiencing too.  I can use
the exact same smb.conf with 3.0.24 and it works fine.  The bug report
is at https://bugzilla.samba.org/show_bug.cgi?id=4673 (down for
maintenance as I type this).

Jeremy Allison requested that I generate some level 10 debug logs which
I have done, just waiting for bugzilla to come back online so I can
submit my logs.

Please keep an eye on the bug report and add anything you feel might be
pertinent.

Thanks,
Tom Schaefer

Subject: [Samba] Difficulty w/Offline Files and Samba 3.0.25

Good morning,

I have a working Offline Files setup w/Samba 3.0.24 (FreeBSD 6.2 host
OS) and a Win XP SP2 client.  Upon updating to Samba 3.0.25, the XP
client's offline cache would show (as viewed via the Offline Files
Folder) that synced files are write-only ('User W' in the Access
column).  When offline, theses files appeared to be available via
Explorer and double clicking would launch the appropriate program, but
would then generate a file not found error.  Reverting to Samba 3.0.24
and resyncing has corrected the problem ('User R/W' in the Access column
and proper access restored when offline).

My smb.conf is attached.  Apart from the 'map acl inherit' parameter,
which I added when upgrading to 3.0.25 at the suggestion of
WHATSNEW.txt, this configuration file has not been changed in several
months.  Any suggestions as to what the cause of this problem could be?
Are any of the recent changes in 3.0.25a likely applicable to this
problem?

Thanks for the help!

It was an off-by-one error in some code I added into 3.0.25.
I've now fixed it in the codebases and it will be in any
subsequent release. If you want the patch for 3.0.25a I've
attached it to this email.

Very, very, sorry for this bug :-(.

Jeremy.
