## $Id: nnrpd_access_wrapper.py 7899 2008-06-22 18:22:07Z iulius $
##
## Example wrapper for support of old Python authentication scripts,
## by Erik Klavon.
##
## This file contains a sample Python script which can be used to
## duplicate the behaviour of the old nnrppythonauth functionality.
## This script only supports access control.
##
## How to use this wrapper:
## - insert your authentication class into this file;
## - rename your authentication class OLDAUTH.
##
## See the INN Python Filtering and Authentication Hooks documentation
## for more information.
## The use of this file is *discouraged*.
## Old AUTH class.
## Insert your old auth class here.
## Do not include the code which sets the hook.
## Wrapper ACCESS class. It creates an instance of the old class and
## calls its methods. Arguments and return values are munged as
## needed to fit the new way of doing things.
class MYACCESS:
"""Provide access callbacks to nnrpd."""
def access_init(self):
self.old = OLDAUTH()
def access(self, attributes):
attributes['type'] = buffer('connect')
perm = (self.old).authenticate(attributes)
result = dict([('users','*')])
if perm[1] == 1:
result['read'] = perm[3]
if perm[2] == 1:
result['post'] = perm[3]
return result
def access_close(self):
(self.old).close()
## The rest is used to hook up the access module on nnrpd. It is unlikely
## you will ever need to modify this.
## Import functions exposed by nnrpd. This import must succeed, or nothing
## will work!
from nnrpd import *
## Create a class instance.
myaccess = MYACCESS()
## ...and try to hook up on nnrpd. This would make access object methods visible
## to nnrpd.
try:
set_auth_hook(myaccess)
syslog('notice', "access module successfully hooked into nnrpd")
except Exception, errmsg:
syslog('error', "Cannot obtain nnrpd hook for access method: %s" % errmsg[0])
