Hi,
I am trying to write a simple interface between Lua and PAM
authentication. I have it compiling and on testing it seems to work
fine if I use modules such as pam_permit, pam_rootok, pam_stress etc,
but it fails for pam_unix.so authentication? The details of errors I
have are as follows:
#lua
Lua 5.1.1 Copyright (C) 1994-2006 Lua.org, PUC-Rio
> require "pamauth"
> pamauth.open("jon","test")
*** Attempting to perform PAM initialisation...
Success
*** Attempting to perform PAM authentication...
User: jon
Password: test
21
Authentication information cannot be recovered
>
Syslog shows nothing. The auth.log shows the following:
Sep 28 11:47:53 mail PAM-warn[4787]: function=[pam_sm_authenticate]
service=[mysql] terminal=[<unknown>] user=[jon] ruser=[<unknown>]
rhost=[<unknown>]
Sep 28 11:47:53 mail lua[4787]: (pam_unix) unable to obtain a password
Sep 28 11:47:53 mail lua[4787]: (pam_unix) auth could not identify
password for [jon]
The user and password exist, but it is like PAM cannot work out the
file format or something? I am trying this under Ubuntu Linux at the
moment, if that will make any difference. Also, I have tried setting
the /etc/passwd and /etc/shadow files to be world writable (777)
without any effect. However if I leave out the name, or give a non-
existent one, the PAM message changes so it appears to work on that
part.
Any suggestion as to what may be the problem.?
Regards
Jonathon
