    SSO Moodle

    I have searched but can't find the answer.
    Our SSO was working a while ago but since we have had a new server, Server 2008R2, all you get is an 'internal server error' message.
    Can anyone point me in the right direction as to what is missing or what I need to do to get this working??
    Most of Moodle is way beyond me so simple answers carefully explaining what I need to do would be very gratefully received!

    @witch:

    Is that the only error message you are getting?

    Is there anything else to the message to do with fastCGI?

    I do feel it could be your installation of PHP which is not working (I could be wrong)

    Have a look at this: Using FastCGI to Host PHP Applications on IIS 7 : Host Applications on the Microsoft Web Platform : Running PHP Applications on IIS : The Official Microsoft IIS Site

    Hope this helps

    I take it you have followed these instructions witch?

    How to Turn Integrated Authentication on

    The File ntlmsso_magic.php (1.9 or above) or oncampuslogin.php (1.8 or below) MUST have NTLM/Integrated Authentication enabled at the server or the page will not work.
    IIS Configuration

    Open up IIS, and find the auth/ldap/ntlmsso_magic.php (1.9 or above) or auth/ntlm/oncampuslogin.php (1.8 or below) file,

    1. right click on the file, choose properties
    2. under the "file security" tab, click on the Authentication and Access control "edit" button
    3. untick "Enable Anonymous Access" and tick "Integrated Windows Authentication"
    4. According to this post, if you are using IIS 7.5 (it comes with Windows Server 2008 R2), you have to select 'Windows Authentication' and click on 'Providers'. This shows a list of enabled providers (Negotiate and NTLM, by default). Change the order so that NTLM is at the top of the list.

    Otherwise I can't help. moodle on apache here!

    Have you checked the IIS log files and/or turned on debug mode in Moodle?

    I don't understand Moodle and I have tried to follow what is going on with only small success.
    It seems that SSO HAS worked since we got our new server, and now it just doesn't.
    I will go through the instructions and do my best tomorrow.
    I will try skell's advice
    Webman - where do I find the log files?
    thanks

    The log file location can be found by clicking a button in one of the tabs in the Properties window of the site/folder in the IIS management console. That's not very specific, because I can't remember It'll be there somewhere though.

    I can't find the file that skell specified but 'anonymous authentication' is showing as enabled.
    I don't know if this is good enough?
    Cannot find any tabs/buttons that show me the log file and I think I have clicked on everything
