Below is /etc/pam.d/dovecot

I am trying to get dovecot to not require password auth if user is already logged in, using pam_alreadyloggedin module

===========================================================================
#%PAM-1.0


@include common-auth
@include common-account
@include common-session

auth    sufficient      pam_alreadyloggedin.so debug no_root
=============================================================================


Here is debug output when I try to log in to dovecot and it fails:

dovecot-auth: pam_sm_authenticate:165 Debugging output enabled
dovecot-auth: pam_sm_authenticate:169 logname = "user"
dovecot-auth: inutmp:261 Can't stat line "/dev/:0"
dovecot-auth: pam_sm_authenticate:193 Found matching records in utmp: 0
