             Summary: ManageSieve sends AUTHENTICATE
                 Key: JAMES-4207
                 URL: https://issues.apache.org/jira/browse/JAMES-4207
             Project: James Server
          Issue Type: Bug
    Affects Versions: master
            Reporter: Felix


James sends ManageSieve capabilities after every successful AUTHENTICATE command.

This was introduced with https://github.com/apache/james-project/commit/1819fddf13c88476a0766ccc91c81d66d14da682.

 

However, the relevant RFC (5804, section 4) states:
response-authenticate = *(string CRLF)
                            ((response-ok [response-capability]) /
                             response-nobye)
                            ;; <response-capability> is REQUIRED if a
                            ;; SASL security layer was negotiated and
                            ;; MUST be omitted otherwise.
I think that all authentication mechanisms supported by James (PLAIN, LOGIN, XOAUTH2, OAUTHBEARER) do not negotiate a SASL layer.

The server must therefore omit the capabilities.

There was a similar discussion here: [https://github.com/thsmi/sieve/issues/480]

I can confirm that the Roundcube webmail client does not expect capabilities and fails to use managesieve with James.
