[Modus] quick question

Title: Message

I am a small ISP with about 800 customers.  We are running windows 2000 but have setup modus to make email accounts automaically for NT users.  Being that we are running windows 2000 and not windows NT should I change the authinication to LDAP instead of NT database?  Does it do anything different?  And how would I setup LDAP?  When I try to stard the LDAP service in modus I get an error in the event log.   Could not connect to the logging database.

I thought Active directory was LDAP
