I think X-LANMAN and X-NTLM would be better choices if we
would have used X-UNIX, etc.  But since all of RFC 2307 is
experimental, it really doesn't matter much.

Yes, these attributes should be administrated by user applications,
not slapd.  They should be loaded via a .schema file.

The hash generation code for userPassword is in one place,

Not yet.  When authPassword is added, there should be a configuration
flag that says "use authPassword instead of userPassword".  Then
the directory authentication services would use authPassword instead
of userPassword and the password modify would likewise update
authPassword instead of userPassword.

Not necessarily.  authPassword can be used with one scheme, just
like userPassword.  One should only use multiple schemes when
replicas don't support the same scheme as the master.
