Hi,I'm still trying to plan out my courier mail setup. Right now i'm trying to figure out which authentication module i want to use. I really like the looks of the userdb stuff (really what i'm looking for is a way to give people mail accounts w/out giving them real user/shell accounts). so userdb looks perfect in that respect. I've also thought about ldap authentication... i don't really know anything about ldap, but i've heard it's very scalable (from the docs i've readon openldap.org it seems that multiple servers can balance the load). The setup i have going on here looks like it could get fairly large(maybe 200,000 users in the long term), but i'm not sure if that justifies ldap or not (especially since i have no existing ldap
Yes, it does. You don't want to use userdb with 200,000 accounts.
directory). Anyway, it looks like courier is able to handle multiple authentication schemes quite nicely, so maybe i could go w/ userdb at first and then if necessary add ldap at a later date. Are my assumptions wrong?
That certainly sounds reasonable. You can launch a pilot with a few hundred accounts and userdb, and once you are comfortable proceed with a full-blown LDAP-based rollout.
