Are PAM modules a viable route and/or one that you'd consider?  I have 
no idea how it would work, but it seems to me that it's a good loosely 
coupled interface from both sides of the problem.  To be honest, I run 
Slackware and PAM isn't included as Patric V. strong believes PAM is a 
security risk, so I can't comment on how easy an implementation might be 
as I've only toyed with it on a few occasions.  I know, however, that 
Samba uses PAM for syncing the passwd/shadow files, so there must be 
some sort of interfacing capabilities native to Samba.
