[Zope-Checkins] CVS: Zope2 - User.py:1.101

[Evan Simpson]

Update of /cvs-repository/Zope2/lib/python/AccessControl
In directory korak.digicool.com:/projects/sites/ZapMedia/ZM-Evolut-Proto/lib/python/AccessControl

Modified Files:
	User.py 
Log Message:
Modified _doChangeUser to leave password unchanged if the 'password' parameter is None.  _changeUser now always accepts "password == confirm == None", and sets 'password' to None if "password == 'password' and confirm == 'confirm'".

This gives Users an unambiguous protocol for both DTML and Python code to change roles/domains without touching the password.  editUser.dtml has a somewhat magical protocol, which users need not worry about.
