PAM and Python2.2

[Janek Neubert]

Hi,


I'm using pyPAM (0.4.2) to authenticate users via PAM. With Debian sarge all
works fine. Unfortunally, I've problems with the same tool on Redhat 7.3.
pyPAM is unable to execute a conversation function and reports:
PAM.error: ('Conversation error', 19)

In /var/log/messages you read:
Aug 27 18:53:51 minipc3 wwwproject(pam_unix)[21675]: auth could not identify
password for [janek]

On my debian, all forks fine. Very strange.
Is this a redhat problem or a problem with pyPAM?

cu & thx janek

The test script:

import sys
import PAM
from getpass import getpass

def pam_conv(auth, query_list, userData):

        resp = []

        for i in range(len(query_list)):
                query, type = query_list[i]
                if type == PAM.PAM_PROMPT_ECHO_ON:
                        val = raw_input(query)
                        resp.append((val, 0))
                elif type == PAM.PAM_PROMPT_ECHO_OFF:
                        val = getpass(query)
                        resp.append((val, 0))
                elif type == PAM.PAM_PROMPT_ERROR_MSG or type ==
PAM.PAM_PROMPT_TEXT_INFO:
                        print query
                        resp.append(('', 0))
                else:
                        return None

        return resp

service = 'wwwproject'

if len(sys.argv) == 2:
        user = sys.argv[1]
else:
        user = None

auth = PAM.pam()
auth.start(service)
if user != None:
        auth.set_item(PAM.PAM_USER, user)
auth.set_item(PAM.PAM_CONV, pam_conv)

print auth.authenticate()
#print auth.acct_mgmt()
sys.exit(0)
