I'm setting up dovecot in OpenBSD OS. The problem is that I can't set up dovecot to use kerberos authentication via bsdauth which is "similar to pam" I try to test dovecot via telnet: telnet localhost pop3 user test +OK pass password -ERR [IN-USE] Temporary authentication failure

and some strings from logs Feb 3 15:02:37 srv-mx-00 dovecot: auth: Error: bsdauth(rodin.m,127.0.0.1): getpwnam() failed: Operation not permitted Feb 3 15:02:46 srv-mx-00 dovecot: pop3-login: Disconnected (auth failed, 1 attempts): user=<rodin.m>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Feb 3 15:29:13 srv-mx-00 dovecot: auth: Error: bsdauth(test,127.0.0.1): getpwnam() failed: Operation not permitted

What am I doing wrong?

Here is the output of dovecot -n
