Well. IMHO that used to be a standard way of doing this when directories 
where not available. Now it is quite common to validate against an LDAP, 
MySQL or whatever server. YMMV. But you are right in that all these 
implementations assume that checking against the local user database is the 
default action.

That would need a reimplementation of some (all?) of the servers. Wouldn't
it? Old ones (cistron, livingston) call getpwnam()|getspnam() to retrieve
the user's encrypted passwords. New ones (freeradius) can alternatively
talk with a myriad of authentication services...
