Very much so. However, if you are starting from an existing Unix
environment (whether it uses LDAP for password storage or not), you
cannot use the Unix-style hashed passwords to authenticate `encrypted
password' SMB connections. A new set of password hashes must be
maintained in parallel, or the LDAP server must store cleartext
passwords and generate the various hashes on demand (you can do this
with OpenLDAP 2.1: much more flexible, but also a much bigger problem
if the database security gets compromised).

LDAP fits into all of this by providing a replicated store that allows
multiple Samba instances to share `PDC' data. In principle, this
should let you set up something like the Windows PDC/BDC fallback
without having to use M$ protocols to synchronise the data.
