Hi,

I think for now you could duplicate the ldap auth file and rewrite:

check()
_valid_login()
_validate_to_host()

You'll need to hardwire some of the values as LDAP auth is hooked into the XOT database (we're working on changing the way this is done so that you should be able to store your Shib config values in XOT db more easily soon!ish)...

As long as you return true and populate

$this->_record = array('firstname' => xxxx], 'surname' => xxxx, 'username' => xxxx);

then I believe that this should work... config.php will take care of the rest, including session_start()

Hi John,

That was the route I was initially attempting, but ended confused as to what I should or shouldn't have included in my 'Shib.php' script.
Could I hack the 'Ldap.php' script for example, just leaving in the public functions getUsername, getFirstname and getSurname to return the values passed forward from the Shibboleth IdP?

Cheers,

Bruce

I'd advise NOT altering the core files (you will then run into upgrade probs in the future for one) but looking in \library\Xerte\Authentication and creating a new Shibboleth authentication class that is abstracted out and should then be able to just slot in...

Then it should only be a case of adding a new authentication method to auth_config

Hello,

We're trying to get Shibboleth working as a method of authentication here.

>From a thread on this forum back in November 2010 (http://lists.nottingham.ac.uk/pipermail/xerte/2010-November/007360.html), and from reading the comments in the integration.txt file, it appears it should be a fairly simple case of editing integration.txt to set the three variables ($_SESSION['toolkits_firstname'], $_SESSION['toolkits_surname'] and $_SESSION['toolkits_logon_username']) to values obtained from the Shibboleth IdP, adding a call "session_start()" at the beginning of the script, and then renaming integration.txt to be index.php.

When I do that and try to log in, the page I get back appears to have a chunk of html missing at the start - see below.
Should I be copying parts of the standard index.php script into the integration.txt version?

Returned html:
