Has anyone gotten a unified Murder and GSSAPI configuration working? The documentation is lacking, to say the least. This is what I'm trying to do: 1 master mupdate server 8 unified frontend/backend servers I want all the servers to authenticate with each other via K5 GSSAPI. Ideally, I would like them to use a shared K5 keytab with the principle name service/murder to communicate with each other. On the mupdate server, in the cyrus.conf file, I have: auth cmd="/usr/bin/k5start -H 60 -l 10h -f /etc/keytab.murder -k /var/tmp/murder.k5.tgt service/murder mupdate cmd="mupdate -m" listen=3905 prefork=1 (k5start is similar to ksrvtgt.) In imapd.conf, I have admins: service/murder On the initial testing backend server, I have the following in imapd.conf: mupdate_server: <mupdate master> mupdate_config: unified mupdate_port: 3905 force_sasl_client_mech: GSSAPI Yet when I switch over the cyrus user, set my KRB5CCNAME to the correctly generated service/murder ticket and try to run ctl_mboxlist -mw, I get the following in my syslog: ctl_mboxlist[13748]: couldn't authenticate to backend server: generic failure ctl_mboxlist[13847]: GSSAPI Error: Miscellaneous failure (Server not found in Kerberos database) Any ideas or pointers at better documentation on how to get this working? -- Huaqing Zheng Beer and Code Wrangler at Large ---- 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
