Hi,
maybe it's me having completely weird ideas, but the existing Google
results for "postfix ldap howto" are not very satisfactory for me:
All I would like to do is to have a separate user base (stored in LDAP)
from /etc/{passwd/shadow} on my Linux box for all email-related issues. So
far I was always annoyed that the default setup of Postfix (openSuSE,
dunno about other distros) uses /etc/passwd to look up users, because that
means evry added mail-user automatically also becomes an SSH user (for
instance) without me intending this. This becomes particularly tricky if
such a user pick "secret" as his/her password.
What I find in the howto(s) are discussions about alias mapping via LDAP
or setting up some catchall user or setting up mail distribution groups.
Far too advanced for me. All I want is LDAP user lookup for incoming mail
and user authentication for outgoing mail. Ideally, I would like to use
two different branches of the LDAP tree for OS logins and mail logins.
Either the info how to do this is very well hidden, or I'm looking for the
wrong keywords, or my idea is so strange that no one's ever done such
nonsense before (hence the apparent lack of documentation), or I simply
missed the right spots in the howto(s).
I turn to this group with some questions:
a) is my idea completely crazy so that I should not do this at all?
b) hoping for a "no" in a):
can someone here point me into the right direction/docs?
c) if someone did this before, can I snaffle some config snippets?
Cheers,
Raimund
