Hi, we have upgraded our servers from debian squeeze to wheezy. So the cyrus packages are now 2.4.16 (former 2.2) Since then we have a few problems: The server were not able to save the message in the sent-folder. This we fixed. But then or beside exists another problem. If I will create a new subfolder via frontend server, following messages appears in the logfile: IOERROR: Mailbox name too long And no subfolder is created. It seems there is a problem with the authentication in our murder setup. cyrus@backend:~$ mupdatetest -u cyrplain -m plain frontend-master.server S: A01 NO "undefined error!" Authentication failed. generic failure Security strength factor: 0 On the backend server everything is working fine. Can you please point me in the right direction. --- snip of frontend-master imadp.conf --- admins: cyrus mupdate_admins: cyrmupdate cyrproxy cyrplain imap_admins: cyrus cyrproxy proxy_authname: cyrplain proxy_password: secret force_sasl_client_mech: plain sasl_pwcheck_method: auxprop saslauthd --- snip of backend imapd.conf --- admins: cyrus cyrmupdate automatix cyrplain mupdate_admins: cyrmupdate cyrproxy cyrplain imap_admins: cyrus automatix cyrplain proxy_authname: cyrplain proxy_password: secret proxyservers: cyrproxy cyrmupdate cyrplain sasl_pwcheck_method: auxprop saslauthd mupdate_server: frontend-master.server mupdate_port: 3905 mupdate_username: cyrmupdate mupdate_authname: cyrmupdate mupdate_realm: ISTA.LOCAL mupdate_retry_delay: 60 Cheers, Nina -- Ing.
