Currently we are using qmail with regular Unix system accounts (with
Maildir boxes), but I'd like not to.
The main reason we use this is because we also use a radius server
(Cistron-Radius) and it authenticates though system accounts.
But ideally I'd like all the accounts to be in an single LDAP directory so
I can keep all accounts in a central location and not have to replicate
information. Also, I'd like the accounts to be maintainable by non-unix
users (either via web interface or Windows). A SQL backend would be nice
too. Also, I'd like SAMBA and SQUID to be able to authenticate through
the same database. I want everything. But I'm not sure about the best
combination of tools.
Any suggestions?
