No problem.

In theory, it would be possible to recreate the steps that the SIA calls
do, but then you are tied to a particular SIA interface.  SIA is sort of
like PAM, an abstracted interface that loads modules to do the work.
There are base (BSD) security, enhanced (C2) security, and audit modules
included with the base OS, and LDAP is available as an add on, plus you
can program your own.

I was going to download the current snapshot to update my SIA minor
cleanup patch (disables post-auth privsep for SIA so at least pre-auth
privsep works, takes out a couple of unnecessary things, makes
everything follow the coding guidelines that I didn't read before
submitting), but the latest snapshot on the FTP site is from 1 Nov, and
I was prompted for a password from the CVS tree.

I don't speak for anybody but myself - that's enough trouble.
