We use a combination of RedHat Advanced Server, sendmail, Eudora qpopper (for pop), University of Washington imapd, Novell's eDir for LDAP access, all stored on a Xiotech SAN.
I don't know all the details, but it can be done. Everything is stored in our LDAP tree, aliases, user accounts, home directories, shell, even ID's for other systems that authenticate to our LDAP tree. It's a very sweet setup. You are welcome to come take a tour. We could trade tours! -- Brad Bendily - CNA Network Specialist Southeastern Louisiana University Phone 985.549.3643 Fax 985.549.5777
