Hello, My cyrus imap server have some troubles with authentification. This problem occured recently, altough cyrus worked like a charm for several months. Here follows few lines of the auth.log file : Sep 26 18:37:25 weg38-2-82-233-114-223 cyrus/imapd[12292]: can't access srvtab file /etc/srvtab: No such file or directory Sep 26 18:37:25 weg38-2-82-233-114-223 cyrus/imapd[12292]: server add_plugin entry_point error generic failure Sep 26 18:37:25 weg38-2-82-233-114-223 cyrus/imapd[12292]: _sasl_plugin_load failed on sasl_server_plug_init for plugin: kerberos4 Sep 26 18:37:25 weg38-2-82-233-114-223 saslauthd[8220]: do_auth : auth failure: [user=gilles] [service=imap] [realm=] [mech=sasldb] [reason=Unknown] Sep 26 18:37:25 weg38-2-82-233-114-223 cyrus/imapd[12292]: Password verification failed Sep 26 18:37:28 weg38-2-82-233-114-223 saslauthd[8220]: do_auth : auth failure: [user=gilles] [service=imap] [realm=] [mech=sasldb] [reason=Unknown] Have you any idea about the problem ?
