Okey, Now with the newly compiled cyrus-sasl-2.1.22, i get another (perhaps better) error message instead. So I guess I had a incorrect blastwave-package config, or strange problem?! Well, with this new sasl2, I have tried Sendmail.conf containing: checkpw_method: saslauthd, or checkpw_method: shadow And running: saslauthd -a shadow -V, or saslauthd -a pam -V But I always get this error in the syslog-logfile, then I try to use MS OE: AUTH failure (LOGIN): user not found (-20) SASL(-13): user not found: checkpass failed Then I run testsaslauthd -u user -p pass, it gives me: 0: OK "Success." So i guess the problem lies between sendmail <-> cyrus-sasl in some way. (I have also created a user with saslpasswd2, the same user that is in /etc/passwd & /etc/shadow, but error is still no luck. But I guess that was unnecessary, but at least I tried it out :-) ) Any more clues of that I'm doing wrong here? TIA, /P
