It struck me as the same as a "Windows NT" authentication source.

We've gotten a *lot* of complaints about using PAM with saslauthd (memory
leaks, instability, etc).  In every case this has been tracked to problems
that originate from the PAM module, not saslauthd.  This makes me very
leery of using PAM for anything that saslauthd offers a legitimate
alternative to.
