WebID Authentication

Hi,
It appears you are working in the "master" branch in git. You should really be working in a version specific branch. The most direct documentation on this is Moving from a master branch to a version branch. For additional resources please see the documentation about release naming conventions and creating a branch in git.
Review of the master branch:

• Remove LICENSE.txt, it will be added by drupal.org packaging automatically.
• Remove "version" from the info file, it will be added by drupal.org packaging automatically.
• The "?>" PHP delimiter at the end of files is discouraged, see http://drupal.org/node/318#phptags
  

  ./webidauth.parser.inc
  

• ./webidauth.module: all functions should be prefixed with your module/theme name to avoid name clashes. See http://drupal.org/node/318#naming
  

  function _webid_auth_access($uid_arg) {
  

• Run coder to check your style, some issues were found (please check the Drupal coding standards). See attachment.

I've attached the report. Also, the coder module detected some issues.
After I enabled your module, I got some notices that I didn't had before. See below:

    Notice: Trying to get property of non-object in user_access() (line 790 of /Users/dicix/work/www/proiecte/drupal7/modules/user/user.module).

I also seem to have some access problems, even though I am user/1. I've attached the screenshots.
