CRAM-MD5 with saslauthd

[Ram]

I am trying to use CRAM-MD5 for password authentication.
The passwords are in ldap.


But the cyrus document here 
https://cyrusimap.org/docs/cyrus-sasl/2.1.23/sysadmin.php   says that I 
cannot use saslauthd with CRAM-MD5 or DIGEST-MD5

Then how do I configure my imap server to use CRAM-MD5 ??

Is there a simple howto ?



Thanks
Ram
