ObjXMPP  Artifact [60f59f8f6f]

Artifact 60f59f8f6f5c4ad58ee9e2c437e6d2893a5ca3996e437ba7eeff5e8e5de72090:

• File src/XMPPExceptions.m — part of check-in [6a3b0a9988] at 2011-02-21 03:09:39 on branch trunk — Add SCRAM-SHA-1 support

  This adds the new base class XMPPAuthenticator and the derived
  classes XMPPSCRAMAuth and XMPPPLAINAuth.
  They are now used for authentication from within XMPPConnection.

  Also adds XMPPAuthFailedException which is thrown in appropriate places. (user: florob@babelmonkeys.de, size: 5635) [annotate] [blame] [check-ins using]
