Hello , of course i am importing without .py . I have checked all paths with sys.path and also check if INN is using same python version with same environment as mine - and yes it is.<br>What i have discovered is that nnrpd_auth.py has a really problem with importing anything except builtin sys module.<br>
Module ldap is not working, module commands is not working ... it will simple print no result ...<br>When i test it trought my test script it will does. When i test it directly with INN i see only "python auth returned wrong result".<br>
When i try to investigate that with try except Exception .. i simple see no error there but null result ... it will simple not call the result... even simple commands.getoutput("ls -l") does not work! :(<br>Only one solution i have found is to import sys module and call popen to open external script .. also writen in python .. which will simple to standart out return result (and which is using module ldap without problem) .. and then i read output in nnrpd_auth and work with that.<br>
Such ugly think , i spent 3 days working with nnrpd_auth.py and nothing worked as i wanted (and i am programming in python for 3 years actually so i dont think i am lame ).<br><br>Thanks! and if someone really will help me to investigate problem i will sent them a package of Czech Beers (Gambrinus,Plzen or Budvar) as i am live in czech republic!<div>

I have created own try, except part to see error, but all i got is : python:<br>
Error: No module named py<br>
I want to know more , i want to know why? There is no other info in logs.<br>

Do you "import module.py" or "import module"? The last one is the right thing to do<br>
inside your scripts. Also check whether paths are correct.<br>
<br>
And in readers.conf, did you try without ".py" too in the python_auth: parameter?<br>
(I do not know whether it is required.)<br><font color="#888888">
