#3 authorizationID not set in CramMD5Server

[Ward K Harold]

In the CramMD5Server.evaluateResponse() method
authorizationID does not get set after successful
authentication.

The following change fixes this problem:

// Compare the received and computed digests
if (!SaslUtil.areEqual(digest, responseDigest))
throw new SaslException("authentication error");

should be:

// Compare the received and computed digests
if (!SaslUtil.areEqual(digest, responseDigest))
throw new SaslException("authentication error");
else
authorizationID = username;
