I am using this module to authenticate using pam: http://code.google.com/p/web2py/source/browse/gluon/contrib/pam.py
I can call authenticate( username , password ) and it returns True/ False. It works for any username but root . My guess is that there is a security restriction in PAM that does not allow to check for the root password.
I need to be able to check the root password. Is there anything I can change in the pam.conf or somewhere else to remove this restriction?
I found the answer to your question, the problem is in the default service.
when you call the function authenticate( username , password ) make sure you pass an appropriate service too. like authenticate( username , password , passwd ) or you can add your custom configuration under /etc/pam.d/
here is an example from the webmin project
#%PAM-1.0
auth required pam_unix.so nullok
account required pam_unix.so
session required pam_unix.so
write the previous lines on a file under /etc/pam.d/ and call it myconfig for example, then pass it s name to the function, and it ll work (it did for me) :D
I had the same issue root was not getting authenticated. Here s the fix.
If you use the service login ,it won t work for root. Use,
#authenticate( username , password ,service= system-auth )
You could use sshd configuration if its a system with ssh server running and should work for root.
authenticate( root , password ,service= sshd )
