User Id Invalid - uninformative error after a fresh installation

Question

I've installed CRM 2013, DB, SSRS and the extensions. After that, I've created an organization. When I attempt to access the newly created organization I'm getting the error as shown below.

The information's as helpful as a chocolate teapot and I have no idea how to proceed. When I misspell the name, I'm getting the error that web page isn't found, so I'm getting the impression that something is up and running.

Suggestions?!

Update

After enabling the Dev errors. Browser says "user id invalid".

As you mentioned in your comment above, it looks like installation issue.

Microsoft recommends that you add the Microsoft Dynamics CRM server to the PrivUserGroup group when you install the Microsoft Dynamics CRM server. If the server is manually removed from the group or if the server was not added during the installation, you experience the problem that is mentioned in the "Symptoms" section in the link below:

However this KB article is for 4.0 but it could be the same issue with 2013 as well. Worth reading.

Update

Also its worth checking application pool.
