Greetings,
We are attempting to implement an auto sign-in ability via a custom sign on page. We use ADFS authentication for all users, but still require NTLM for some SharePoint services (search). We came across this solution on codeplex (http://spautomaticsignin.codeplex.com/) and it works great, but we still need the ability to leverage the default sign in page when needed (say if we federated to a 3rd party).
However it appears that once you set the custom sign in page on the web application that the default.aspx sign in page is no longer accessible. Trying to browse to it will just try to kick you back to the custom sign in page with an extra '_login' in the URL:
(https://sharepoint.2008r2.local/_login/_login/default.aspx?ReturnUrl=%2f_layouts%2f15%2fAuthenticate.aspx%3fSource%3d%252F&Source=%2F)
I would think even with a custom sign in page configured that you would still be able to browse to the default url properly, but perhaps my understanding of it isn't strong enough.
Perhaps someone here has some insight?
Thanks.
