Hello, i transfered my murder from some x86 VM machine to some real x64 machines, and I cant get the frontend/backend and mupdate servers to talk to each others. imtest only works with the -t option. I use pam and a mysql DB with hashed paswords. Local testsaslauth works and also i can do a mupdatest with the same parameters as in the imapd.conf. on the frontend I have these messages repeating, 08:21:00 frontend-A1 mupdate[5198]: couldn't connect to mupdate server Feb 4 08:21:00 frontend-A1 mupdate[5198]: retrying connection to mupdate server in 25 seconds Feb 4 08:21:12 frontend-A1 mupdate[5196]: couldn't authenticate to backend server: no mechanism available also I can find this line frontend-A1 saslauthd[1617]: pam_unix_acct(imap:account): could not identify user (from getpwnam(albert@xxxxxxxxxx)) looks like pam tries to look for a local user? Since I am using as mech only PLAIN, how can I force the deamons to use TLS to talk to each other? cheers rupertt ---- 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
