exim runs as user exim, keytab is standard /etc/krb5.keytab
-r--r----- 1 cyrus exim 1514 21. Dez 2015 /etc/krb5.keytab
No changes between 4.91 and 4.92, both tried on the same host.
Now, we build exim-4.92 with 2 files from 4.91:
./src/auths/cyrus_sasl.h
./src/auths/cyrus_sasl.c
And … gssapi with cyrus-sasl works!
So there are some changes breaking at least our setup.
Unfortunately a quick look at the diffs doesn't unveil the relevant changes
to our eyes.
