Running "exim -d+auth" to get debugging information, with enhanced
details on authentication, would probably be informative.

Since you're using Kerberos and don't mention it, I take it that you've
created the server principal and put it somewhere that Exim will find it
(via PAM?) SMTP uses "smtp/" principals instead of the "host/"
principals normally used for authentication for PAM sign-in.

Eg, I run "ktutil -k /etc/kerberos/tabs/exim.keytab list" and see
principals for "smtp/smtp.spodhuis.org@???" with various
ciphers.

I use Cyrus SASL, not PAM; but on a Debian-derived system, I see a
man-page for pam_krb5(8) which mentions the optional "keytab" attribute.
You'd probably want to get an smtp principal into a file readable by
the Exim running process and tell PAM to use that file for Exim with the
keytab attribute.
