Rails - May 2006 - Getting Net::IMAP to work with PLAIN auth type...

Hi there,

            I''m new to rails and I''ve been successful
tinkering around but
am miffed by the process of trying to connect to my mail server to receive
email for ActiveMailer parsing.  I''m hosted on TextDrive and have read
the
following article on the RubyonRails wiki:
http://wiki.rubyonrails.com/rails/pages/HowToReceiveEmailsWithActionMailer.

 

I want to connect to my TextDrive hosted email account using Net::IMAP but
the problem is that the authentication method is ''PLAIN.'' 
I''ve been
searching to find a good example of how to connect to an IMAP mailbox using
the PlainAuthenticator, but I haven''t come up with anything.  Can
anyone
provide a code  example of how to connect to an IMAP mailbox using the
''PLAIN'' authentication method?

 

Thanks,

-Alex

Use the ''login'' method instead of
''authenticate''.

This won''t work if the IMAP server doesn''t support LOGIN. 
Mine doesn''t.

That''s because there isn''t one.

I wrote an implementation for IMAPCleanse, but haven''t yet submitted  
a patch to ruby-core because it should only work on SSL sockets.

Here it is:

##
# RFC 2595 PLAIN Authenticator for Net::IMAP.  Only for use with SSL  
(but not
# enforced).

class Net::IMAP::PlainAuthenticator

   ##
   # From RFC 2595 Section 6. PLAIN SASL Authentication
   #
   #   The mechanism consists of a single message from the client to the
   #   server.  The client sends the authorization identity (identity to
   #   login as), followed by a US-ASCII NUL character, followed by the
   #   authentication identity (identity whose password will be used),
   #   followed by a US-ASCII NUL character, followed by the clear-text
   #   password.  The client may leave the authorization identity  
empty to
   #   indicate that it is the same as the authentication identity.

   def process(data)
     return [@user, @user, @password].join("\0")
   end

   private

   ##
   # Creates a new PlainAuthenticator that will authenticate with  
+user+ and
   # +password+.

   def initialize(user, password)
     @user = user
     @password = password
   end

end

if defined? OpenSSL then
   Net::IMAP.add_authenticator ''PLAIN'',
Net::IMAP::PlainAuthenticator
end

PS: This is really a question for ruby-talk.

Eric,

So LOGIN and PLAIN authentication are two different things?  Why  
doesn''t PLAIN authentication work then?  I thought it was some sort  
of bug.

Which one regular GUI email clients use?

cheers,
daesan

PS: By the way, TxD does support LOGIN.

LOGIN sends the user and password as separately.

PLAIN sends the user and password in one ASCII NUL separated line  
(and allows you to say things like "use this users password and get  
that user''s email")

Net::IMAP doesn''t have an authenticator for PLAIN.  Writing one  
wasn''t hard.
> Which one regular GUI email clients use?
Mail.app supports password (probably LOGIN and PLAIN), CRAM-MD5,  
Kerberos 4/5 and NTLM.  I use SSL + PLAIN.

I''ve been using SSL + LOGIN since PLAIN didn''t seem to work. 
I
didn''t realize that the authenticator was not implemented.  Thanks  
Eric!  I wouldn''t have figured that out by myself!

best,
daesan
