Hi! If I have on the 'remote' backend a line such as sasl_mech_list: DIGEST-MD5, PLAIN, LOGIN in /etc/imapd.conf, all proxy operations fail with a message such as: Server(s) unavailable to complete operation and in the 'frontend' log: Mar 7 15:08:04 m2cn1t imap[21585]: Doing a peer verify Mar 7 15:08:04 m2cn1t imap[21585]: Doing a peer verify Mar 7 15:08:04 m2cn1t imap[21585]: received server certificate Mar 7 15:08:04 m2cn1t imap[21585]: starttls: TLSv1 with cipher AES256-SHA (256/256 bits new) no authenti cation Mar 7 15:08:04 m2cn1t imap[21585]: couldn't authenticate to backend server: no mechanism available and in the 'backend' log: Mar 7 15:08:04 m2cn2t imap[31010]: executed Mar 7 15:08:04 m2cn2t imap[27757]: starttls: TLSv1 with cipher AES256-SHA (256/256 bits new) no authenti cation However, if I have a line such as sasl_mech_list: DIGEST-MD5 everything works perfectly, there's nothing special in the frontend log, in the backend log: Mar 7 15:09:20 m2cn2t imap[341]: executed Mar 7 15:09:21 m2cn2t imap[336]: login: m2cn1t.mappi.helsinki.fi [128.214.205.51] cyrus DIGEST-MD5 User logged in What is going on? It even appears that plain text logins to the 'frontend' /do/ work, even while they aren't mentioned anywhere in the config file. --Janne -- Janne Peltonen <janne.peltonen@xxxxxxxxxxx> ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
