You are right, just did tcpdump, sieveshell does connect and authentication fails (but the output is "unable to connect to server"). I have recompiled security/cyrus-sasl2-saslauthd to include security/krb5: # make showconfig ===> The following configuration options are available for cyrus-sasl-saslauthd-2.1.28: DOCS=off: Build and/or install documentation HTTPFORM=off: Enable HTTP form authentication OPENLDAP=off: Use OpenLDAP SASLDB_IN_VAR=off: sasldb in /var/db/sasl2 ====> GSSAPI Security API support: you can only select none or one of them GSSAPI_BASE=off: GSSAPI support via base system (needs Kerberos) GSSAPI_HEIMDAL=off: GSSAPI support via security/heimdal GSSAPI_MIT=on: GSSAPI support via security/krb5 ====> Experimental SASLdb authentication module: you can only select none or one of them BDB1=on: Berkeley DB 1.85 support BDB=off: Berkeley DB support GDBM=off: GNU dbm library support LMDB=off: OpenLDAP Lightning Memory-Mapped Database support ===> Use 'make config' to modify these settings ...but no success. It would be great to have clearer guidance on this issue... -- Janos Dohanics ------------------------------------------ Cyrus: Info Permalink: https://cyrus.topicbox.com/groups/info/T7345c00a04173773-Me2b619eb0f7e3c6121a70a98 Delivery options: https://cyrus.topicbox.com/groups/info/subscription
