Ldap, Pam, Nss, Samba

[Thom Paine]

I have a server that I use as a domain controller with samba. It's
fairly simple, I don't have ldap or pam or nss.

I need to add ldap functionality to it, and I also need to make global
address books available to the Outlook users for a new email gateway
we will be using.

Is open ldap all I need? I've been reading samba 3 by example and am
unsure what all I need to get going.

Anyone have some time to communicate with me off list about this? On
list is fine too, I jsut didn't want to add too much noise.

Thanks.
