Has anyone come across a situation (in SP2013) where accessing
Gives "Sorry this site hasn't been shared with you", yet any other address, including the address of the welcome page that this is supposed to redirect to, works fine?
http://myserver.domain.com:1234/ - another web application, works fine
http://myserver.domain.com/sites/Site1 - another site collection on the initial web application, works fine
http://myserver.domain.com/pages/home.aspx - the home/welcome page for the initial site, works fine
http://myserver.domain.com/_layouts/settings.aspx - the settings page for the initial site, works fine
http://myserver.domain.com/SubSite/ - a sub-site of the initial root site, works fine
The ONLY URL that causes an issue is
http://myserver.domain.com/. I'm authenticating as the site administrator, but it doesn't matter who I do it as, including the farm account.
There's nothing odd in the ULS log, I've even tried debugging it, but all I know is that for that site it's called
SPFederationAuthenticationModule.OnEndRequest whereas for every other URL it doesn't call that.
