Hi list,

I’m trying to setup PAM authentication for nginx and I’m wondering if it  
is possible to authenticate using pam\_unix.so…

Here is the content of my /etc/pam.d/nginx file:  
@include common-auth  
@include common-account

In auth.log, I see some errors:  
Jul 7 12:39:14 eucalyptus unix\_chkpwd[1312]: check pass; user unknown  
Jul 7 12:39:14 eucalyptus unix\_chkpwd[1312]: password check failed for  
user (tonio)  
Jul 7 12:39:14 eucalyptus ker process: pam\_unix(nginx:auth):  
authentication failure; logname= uid=33 euid=33 tty= ruser= rhost=  
user=tonio

But this is not helping a lot.

Maybe some of you have an answer for me? 🙂

Thanks,

Antoine Nguyen.
