In my early testing of SharePoint 2013, I ran across an extremely annoying “bug.” If you attempt to log into a site that has not been “shared” to you by a Site Collection Administrator (SCA), you receive the following error message:

OK…fair enough. But the annoying part is that there is no way to log out of the current session. While testing Claims Authentication in SharePoint 2013, I would often test logging in with an FBA user and run across this issue. The headache for me was that I was unable to sign in as a Windows SCA and make the appropriate change. I tried closing down all sessions of Internet Explorer (IE), waiting for it to “timeout,” etc. The only workaround I was able to use was to open an InPrivate session in IE and log in there:
But even that is still a hassle if you are testing several different areas that involve logging in and out with different authentication methods and permission levels. Fortunately, I was able to find a somewhat easier method that will allow you to sign in as a different user. If you append the following string to the URL, you are logged out and taken back to the default sign-in page:
So, in my case, I changed it from this:
After that, I was finally able to get back here:To make the process faster, you really only need to replace everything after “AccessDenied.aspx?” with “loginasanotheruser=true” and it will work. I’m really hoping Microsoft adds something to the UI to make this process better, but for right now the method above is your best bet.
