Sort of, more or less, and not really.  AD contains an LDAP server
component,  but it piles of a lot of proprietary RPC stuff and some
schema/structures of its very own.   But you can drive PAM/NSS against
AD with a bit of fiddling.

Yes, with a Samba >2.2.3 PDC you can use an LDAP "SAM".  M$ workstations
join the domain, creating objects in the LDAP Dit,  UNIX<->M$ password
sync is a pretty trivial affair.

Yes.  Outlook can query but not update an LDAP address book. Netscape
(I'm told) can do both.  Clients like IMP or Evolution work very will
with LDAP address books.  It works nicely if your user base is stored in
LDAP as you get and address book of them automatically.

You can also control sendmail (aliases, mail routing, access control,
generic table, virtusers table) from a central point without rebuilding
hash files, distribute /etc/printcap information, etc... It is much
nicer as the network grows than managing dozens upon dozens of config

that you might find helpful.

Some people like "Directory Administrator" but I'm afraid there isn't a
tool yet that does it all.  I do alot of work in gq, and I've written a
PHP front end for our specific needs with I'd be willing to send but I'm
afraid. it may be useless to anyone else.

The trouble is (for us) not many of the tools deal with posixAccount +
sambaAccount objects which all of our users are.
