ObjXMPP  Artifact [3b4c3d710b]

Artifact 3b4c3d710b721f09991e79e48dd21f9d59f3fa6d958e520844272404a68405ac:

• File src/XMPPPLAINAuth.m — part of check-in [0aab2fde67] at 2011-09-18 19:33:19 on branch trunk — Fix XMPPAuthenticator to support non-optimized message flow

  While RFC6120 allows and encourages sending data with the success
  message it is also legal to send the same data as a challenge and
  await an empty response. This rework honors that fact. (user: florob@babelmonkeys.de, size: 2143) [annotate] [blame] [check-ins using]
