I'm mostly just a lurker but I don't see how a search of /etc/passwd (or 
nss at least) can be avoided.  When a user logs on to a Samba server the 
smbd runs under their UID which comes from the /etc/passwd file (or some 
other nss source).  Calculating the RID from this already know value 
seems the most efficient process possible IMHO.  I see nothing wrong with 
the accounts in the password database.  It is still security context 
information, not really an different than having entries (uids) for 
things like database engines or messaging software.
