Cyradm authentication failure

[Kai]

Hi,Oliver,
 Thanks for your reply.
 My Cyrus-sasl was configured only supports PLAIN and LOGIN.So ,I tried -=
-auth login and --auth plain.
 I got the same error message after I inputed "cyradm --user cyrus -auth =
login" attempted to login.

>>Login failed: authentication failure at /usr/lib/perl5/site_perl/5.8.0/=
i386-linux-thread-multi/Cyrus/IMAP/Admin.pm line 114
>>cyradm: cannot authenticate to server with login as cyrus

But ,in the auth.log, This line disappeared.

>>>>Apr 24 20:25:51 server perl: No worthy mechs found

and ,after I ran "cyradm --user cyrus -auth login",the application seemed=
 to  be hold ,no new logs.

any ideas ?

Thanks.
