If you only want to dump a few auth cache entries, you can just
authenticate with a bad password.  When a different (and possibly correct
password) is supplied, there will be a cache miss and the new credentials
will be cached.

 	echo "1 login someuser badpassword\n2 logout" | netcat --ssl your-imap-server:993
