[Samba] RE: Sync passwords unix/smb with FDS backend?

Sorry about the acro, I am working with Fedora Directory Server (ldap).
Currently user passwords stored in FDS can be changed from netatalk
(apple protocol), FDS web interface, or unix/passwd via the PAM
interface. To hit all three of these areas I would think that the
password sync would need to somehow be down in FDS.
Looking forward I would like to find an ldap solution. Anything else
will cause additional steps when I add new users to the network.
I will read through pbedit but unless I can trigger it through ldap I
don't know what good it will do.

Scratch my last message about FDS; I was thinking of Apache Directory 
Server.  FDS is pretty mature.  Sorry about that.
