It appears my last entry was not accepted, so I am rewriting.....

I started with a clean server, clean IIS 7.5/MSSQL 12/.Net 4.0/Win Server 2008 R2 and followed Chris Hammond's 4 part video install to the letter. DNN 7.3.4 successfully installed. I then enabled Google Authentication, entered my Google Developer credentials. As before, I get the Google consent screen but get the below error when DNN attempts to use Google's returned information.

Does anyone have this module working? Is there no better documentation.... any other configuration settings I am missing? Please assist....

Hello,

I appreciate the links, however I am way beyond your suggestions. Again, Google is acknowledging my request, it is the DNN module throwing the error. Is there no one else with an intricate knowledge of this DNN base module that can assist? I find it very hard to believe a default DNN module has so little documentation. Does no one have any better suggestions than a simplistic install overview?

Hello,

I was working on this today and discovered that Google has updated the information it requires (without documenting it well) , after a fair amount of legwork I found the issue:

When you create an oauth project (i.e. https://console.developers.google.com...), google generates you a project id e.g. "scientific-reef-824". If you click that project id, you will see the main administration section and you can create a client ID. By default this generates a project name (in my case "dotnetnuke"), as well as the necessary keys. At this point it seems you have everything you need, but if you just add the clientID and client secret into DNN's google auth provider you will get the errors above.

To make everything work, you need to click the "Consent screen" section of the Google Developers Console for your project. Look under APIs & auth in the left navigation and select Consent screen. Update the product name field to match the project id i.e. in my case I changed "dotnetnuke" to "scientific-reef-824" and everything worked
