Impossible authentication at first attempt

Steps to reproduce :

• Authenticate against a first server (i.e. intranet.nuxeo.com)
• Menu > Disconnect
• Set another server (for example : mobile-demo.nuxeo.com)
• Use a valid login / pwd
• On authorization page, Safari, click "Authorize"

Expected : going back to the application as an authenticated user
Actual result : The screen doesn't move

Workaround : after these steps above
Click on "authorize" again
The login/pwd page is shown with empty field
Fill with the same login/pwd then "login"
> JSF "not found page" is displayed in safari
Click on "ok" (going back to the app)
Connect
Authorize
> back to app, authenticated
