[Samba] Truncated Directories

[Wojciech Giel]

Hi,
I have running samba PDC/BDC with ldap backend on debian and external home
directory server (samba member server) on solaris.
I'm using zfs as a file system for home directories.

When I access home directory on windows some directories are truncated to
old dos name length. main problem is with snapshotting directory where unix
name is
ex.
"zfs-auto-snap:hourly-2010-06-28-11:00"

under
Windows:
ZYV2FC~H

what samba options should I add to my smb.conf to avoid such behavior.
thanks
