I was referring to *per site* customisation.  Why should the method of

Its not reluctance, it simply won't happen.  But I don't mind assisting
this (very neat) concept by providing the requisite hooks for some
external program/module to do the dirty work.  I think that PAM modules
provide a nice way to do this, without needing to modify anything in
smbd *at all*, and I'm willing to provide 'exec' hooks as described in
earlier e-mails.  (People use pre/postexec for much of this stuff
