[Samba] sharing samba smbpasswd

[Dean Clapper]

Is there a way to share smbpasswd (samba user name and password file) 
between multiple servers.  The servers are not on a domain controller, NIS 
nor ldap. 

We have 2 - 3 redhat samba servers just for network share drives.  Instead 
of managing passwords and user names on multiple systems, I'm trying to 
leverage one machine and use its logins and passwords for all samba 
machines.

Is there a good way to implement this strategy configuring the smb.conf file 
or is this going to require a different mechanism?

Thanks
Dean
