Previously with samba you could have (and probably needed to have) the 
user stored in /etc/passwd and where ever you stored the samba users 
(ldap etc)
Now with AD, you *cannot* have a local user on a Unix machine that also 
exists in AD, the Unix tools just cannot cope with this, i.e. getent 
will not know which 'user' to show the info for, when setting 
permissions with chmod which user is the owner - the local one or the 
one in AD. You just create all the users in AD and forget /etc/passwd to 
a certain extent.

Yes, I think you are, What I meant is that there is nothing, datawise, 
stored in PAM.
