[Zope-Checkins] CVS: Zope3/lib/python/Zope/Server/Authentication - DictionaryAuthentication.py:1.1.2.1 IAuthentication.py:1.1.2.1 IUser.py:1.1.2.1 SimpleUser.py:1.1.2.1 __init__.py:1.1.2.1

[Stephan Richter]

Update of /cvs-repository/Zope3/lib/python/Zope/Server/Authentication
In directory cvs.zope.org:/tmp/cvs-serv15879/Authentication

Added Files:
      Tag: Zope3-Server-Branch
	DictionaryAuthentication.py IAuthentication.py IUser.py 
	SimpleUser.py __init__.py 
Log Message:
Added a most trivial Authentication mechanism for two reasons:

1. Allow us easy testing of the server framework.
2. Support for non-Zope authentication, so that the servers can be used
   independently of Zope.
