Memory leak on ngx_http_auth_pam_module

[Sergio Talens-Oliag]

This weekend Neil Chintomby <nchintomby at gmail.com> reported me a bug on the
ngx_http_auth_pam_module; the problem was that the current code was not
calling pam_end() when there was an authentication failure, returning without
freeing the memory allocated by the pam transaction operations.

The updated code is available on:

  http://web.iti.upv.es/~sto/nginx/ngx_http_auth_pam_module-1.2.tar.gz

Users of the module should upgrade if they want to avoid the memory leak.

  Sergio.
