I think the older format got dropped along the way. Are the user accounts OK? You could prob use "pdbedit -w" (from the old version) to dump the accounts to a text file. And then maybe write a script (perl has a nice split command) to parse the file into a list of machine names. And then run something like for i in `cat thelist.txt` do smbpasswd -x $i smbpaswd -m -a $i done The other option may be to use pdbedit to dump the passwd to a text or TDB file, backup /etc/smbpasswd and then use pdbedit (to reimport the accounts. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba

For example, to import/export accounts from an old |smbpasswd| database to a /|tdbsam|/ backend: 1. |root# |*|pdbedit -i smbpasswd -e tdbsam|* 2. Replace the /|smbpasswd|/ with /|tdbsam|/ in the /|passdb backend|/ configuration in |smb.conf|.

From: Steve Wolfe on 24 May 2010 18:10 Perfect! On the test server, I just upgraded, did 'pdbedit -i smbpasswd -e tdbsam', and everything seems to have worked. Thank you very much. steve On Mon, May 24, 2010 at 3:00 PM, Gaiseric Vandal <gaiseric.vandal(a)gmail.com>wrote: > On 05/24/2010 04:46 PM, Steve Wolfe wrote: > >> I have a fairly old Samba server, 3.0.25, on CentOS 4.8.
