I'll immediately confess that I haven't been following all the detail,
and that I'm unfamiliar with much of the detail.

But can I just check a few points?  The perspective is "can it accomodate
our current working and its possible evolution?"  Any evolution will
_have_ to be gentle.  (Saying "you shouldn't start from here" isn't an

Does the phrase "/etc/passwd" include, say, NIS and/or perhaps other
technologies, as directed by PAM? 

Will we be able to use PAM's password maintenance function (currently just
"") to maintain (typically from UNIX) multiple parallel
incarnations/encryptions of the password (e.g. UNIX, Lanman and NT) of a
single logical password?  Probably something like:
   other   password required       /path/to/
   other   password required       /path/to/pam_<blah_samba_blah>.so
(hoping that both work or both fail!).

What other questions should I be asking? :-)
