Hi,

Now after having workaround the bug of scanning all LDAP users for each

In some workstation log files i can see something like this :

This is almost certainly bug 6776 which I just
committed a fix for.
I'm planning a back-port, what specific Samba
version do you need the fix for ?
Jeremy.
Thanks for this fix, i've patched my Samba 3.4.2 with your fix and the
locktest2 works fine... Actualy i can't say if this fix solve my
problem, i've disabled mounting CIFS on my linux boxes because my
student can't compile on CIFS share (cf my message related to this
problem), so for instance i've tranformed my CIFS shares in NFS
shares.... it's less secure but it works...
But the bug 6776 describe a behavior really near of my problem. I will
tell you if i can re-enabled CIFS on my linux boxes a day !
Thanks for your fix !
Bruno
