Hi,
I am facing with a problem to which I cannot find a proper key for days. I
read the docs and browsed the google in vain. I'd welcome every helping
hint.
I'm using debian testing linux distribution. I would like to achieve that
when a mail is received it should be delivered in the user's home/Maildir,
which is an openafs export.
The problem is that upon a mail reception when exim4 forks a new process
and changes uid according to the user the mail should be delivered to, it
does not request for neither a kerberos5 nor an openafs ticket, and thus
cannot write the mail in home/Maildir/new/ .
However, if the uzer is logged in (and has the proper credentials) when a
mail is received, it is properly written to the home/Maildir/new/
directory. It makes me have a feeling PAM is not properly configured for
exim or exim doens't digest it as I expect.
The output in /var/log/exim4/mainlog:

In /etc/pam.d/exim I have (just to be sure, there is a symlink
/etc/pam.d/exim4 -> /etc/pam.d/exim) :
auth [success=ok default=1] pam_krb5.so ignore_root debug
auth [default=done] pam_openafs_session.so debug
account required pam_krb5.so ignore_root debug
session optional pam_krb5.so ignore_root debug
session optional pam_openafs_session.so debug
Thanks for your help.
Bests,
