I know this is off topic, but it has to do with authentication and I do use RADIUS. I was hoping someone could help get me pointed in the right direction: I run a moderate sized ISP (20,000+ customers). We currently use Radiator for dial-up authentication. I was wondering if there are solutions out there which integrate Radius (or LDAP, or whatever is the appropriate piece) along with Sendmail and POP3 services. What I'm looking for is a way to distribute e-mail systems across multiple servers with a common authentication (and user directory) scheme. I'm just starting to read and understand about LDAP, but I'm being told it's an important part of trying to implement. I am sure other people have run into this, and I'm curious how they've attacked the problem. I apologize for the off-topic post. Reply off-list (or, if possible, provide me with a mailing list that discusses these issues).
