Hi All,  
I’m trying to authenticate to my imap server using the Net::IMAP  
library.  
i’m doing this:

require ‘net/imap’  
imap = Net::IMAP.new(‘[my.server.com](http://my.server.com)’)  
#i get an imap object back  
imap.authenticate(‘LOGIN’,‘user’,‘password’)  
and at that point there’s a pause then i get:  
Net::IMAP::NoResponseError: encryption needed to use mechanism

my imap server is set to accept these sasl authentications:  
plain login

and my cyrus log says this:  
LOGIN [SASL(-16): encryption needed to use mechanism: security flags do  
not match required]

any ideas how to enable the correct authentication methods on this?

many thanks for reading,  
cheers.

You probably need to use an SSL connection. LOGIN sends a  
recoverable password.
