I have a functioning Cyrus server with IMAP set up to require SSL and use CRAM-MD5 authentication. I'm not having much luck adding webmail functionality---login attempts result in this error:
Bad request: IMAP server does not appear to support the authentication method selected. Please contact your system administrator.
I believe I have properly configured squirrelmail, using /etc/squirrelmail/config/conf.pl In particular, the server and port are set correctly (i.e., to values that work fine with my mail client), authentication type is cram-md5, TLS is on, and server software is set to macosx. Webmail is enabled in Server Admin. Squirrelmail and Cyrus are communicating (a little): the IMAP log shows this:
Nov 3 17:20:20 m204 imapd[17523]: imaps TLS negotiation failed: localhost[127.0.0.1]
Nov 3 17:20:20 m204 imapd[17523]: Fatal error: tls_start_servertls() failed
Any ideas what the problem could be? TIA!
