So I'm setting up cyrus-sasl 2.1.22 on a Linux box, specifically RHEL4. When testing it out with testsaslauthd I keep getting this: 0: NO "authentication failed" log shows this: saslauthd: do_auth : auth failure: [user=blah] [service=pop] [realm=OUR.REALM] [mech=kerberos5] [reason=saslauthd internal error] Yet my Kerberos server clearly shows it thinks everything is ok: auth1 [xxx] [ID 254627 user.info] $DLFDDFLJ, AS: ticket issued: authtime 1154540343, host=IP (FQDN), client=blah@xxxxxxxxx, server=krbtgt/OUR.REALM@xxxxxxxxx I tried running saslauthd with the -d flag and it really doesn't seem to give me any more details than I already have. Ideas?
