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 read
on 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
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?
If there is any chance at all that you may eventually want your users to
have the same username/password for other services (FTP, shell, Web
applications, etc), then by all means, use LDAP. As Sam said, you can
get things going and learn Courier with a simple userdb setup but you
need to start digging into OpenLDAP soon to and tame that beast.
