Following your suggestions I mover all over my cyrus configuration. If I execute: testsaslauthd -u username -p secret -f /var/spool/postfix/var/run/saslauthd/mux I can autenticate all my users via SASL. However if I log to the POP server (enabled, and listening both IP and IPV6). I get in the syslog correo cyrus/pop3[10493]: badlogin: localhost [127.0.0.1] plaintext atarallo SASL(-13): user not found: checkpass failed I checked both using username and username@xxxxxxxxxxxxx as the username for POP3 My /etc/saslauthd.conf ldap_servers: ldap://localhost ldap_bind_dn: cn=Manager,dc=MyCompany,dc=com,dc=uy ldap_bind_pw: MyCompanySecret ldap_scope: sub ldap_search_base: ou=People,dc=MyCompany,dc=com,dc=uy ldap_auth_method: custom ldap_filter: (&(objectClass=inetLocalMailRecipient)(uid=%U)) In my /etc/imap..conf I have virtdomains: yes defaultdomain: correo.MyCompany.com.uy Any help is appreciated.
