I've tried searching the forums for a definitive answer on this, and the closest thing i found was here .

What we are trying to accomplish is having debian sarge boxes at several company locations. These servers will server as a file server/email server/and domain controller for each location. We're hoping that this can be accomplished with samba and the windows clients authenticating against the zimbra LDAP, as opposed to AD.

Is this possible? And if so, can you point me in the right direction?
