[ILUG] Kerberos auth or ssh?

[Deim Agoston]

Hello!

Now I'm completely confused. One of our customers said they
want a centralized authentiacation mechanism. I thought about
LDAP. But when I went there they told me they want to keep
the passwords seperated at the mail, proxy etc servers and
what they want is authentication of clients on the internal
file server. So my next thought was ssh keys or kerberos
authentication (shame, shame I used it under NT once
when the client stucked with NT on the intranet). So,
I used it once and was very impressed by this. So, my
question is: is there anybody who can tell me wheter ssh can provide
the same functions as kerberos? I mean centralized authentication
and so on. I have set up pop3s several times as well as 
imaps and now sftp is
in openssh but I never used it in a situation like this. Oh, yes!
I found heimdal in Debian which has been said that compatible 
with Kerberos 5 which I want to use instead of the free Kerberos
(kth-kerberos).
Bye,
Ago
