Hello Julien, ALL
I have reproduced steps, to show you sample on another module and its
results in INN (becouse i really like to solve this :)
Here is part from nnrpd_auth.py module autheticate(args) which is called
when authentication begins:
part from readers.conf :
*auth "pdg" {
python_auth: "nnrpd_auth.py"
}*
part from nnrpd_auth.py: (here you can also see how i solved problem with
ldap module, i am calling external script and reading result from its
standard output - commented lines)
*def authenticate(self, attributes):
"""Called when python_auth is encountered in readers.conf"""
# just for debugging purposes
syslog('notice', 'n_a authenticate() invoked: hostname %s, ipaddress
%s, interface %s, user %s' % (\
attributes['hostname'], \
attributes['ipaddress'], \
attributes['interface'], \
attributes['user']))
# do username passworld authentication
#if 'foo' == str(attributes['user']) \
# and 'foo' == str(attributes['pass']):
# syslog('notice', 'authentication by username succeeded')
# return ( self.authcodes['ALLOWED'], 'No error', 'default_user')
#else:
# syslog('notice', 'authentication by username failed')
# return ( self.authcodes['DENIED'], 'Access Denied!')
#import os
#result = int(os.popen("%s %s %s"
%("/opt/pdg/newsauth.py",str(attributes['user']),str(attributes['pass'])),
"r").read())
#if result == 1:
# syslog('notice', 'authentication by username succeeded')
# return(self.authcodes['ALLOWED'], 'OK')
#else:
# syslog('notice', 'authentication by username failed')
# return ( self.authcodes['DENIED'], 'FAILED')
import commands
result = commands.getoutput('ls -l')
syslog('notice', result)
*And now comes my test.py where i am testing my nnrpd_auth.py:
*from nnrpd_auth import *
myauth = AUTH()
print
myauth.authenticate({'user':'boss','pass':'supersecret','interface':None,'ipaddress':None,'hostname':None})
*
As you can see my test.py is calling autenticate method same as INN is
calling when auth begins.
Here comes the result from my test.py:
-- syslog level: notice message: nnrpd authentication class instance created
** set_auth_hook for <nnrpd_auth.AUTH instance at 0xb7eb424c>
-- syslog level: notice message: authentication module successfully hooked
into nnrpd
-- syslog level: notice message: nnrpd authentication class instance created
-- syslog level: notice message: n_a authenticate() invoked: hostname None,
ipaddress None, interface None, user boss
*-- syslog level: notice message: total 104

Please note the syslog result .. which is this part from nnrpd_auth.py :
*import commands
result = commands.getoutput('ls -l')
syslog('notice', result)
*And now please note the result from INN where result is completely ignored
