I have created a web application with Forms based authentication and Windows authentication . When i login into site i get a Custom sign in page where there is a drop down box to select either windows or Forms .
My Requirement is now however to create a custom login page where if the user is from same AD will automatically log into site else will be send to a page where he can specify the form based credentials.
Please provide your Suggestions or Answers to execute it.
What I usually do is create a custom login page based on the existing SharePoint FBA login page. I simply add an extra link to this page, call it "Employee Login", "Windows Login" or something similar. I then point this link to the built in SharePoint Windows Authentication page. External users can login with their FBA credentials. Internal users can click the link to login.
This gets rid of the drop down, so you have a single login page.
Arsalan is correct - you can't really do this automatically, because if you want to "test" a user for windows authentication - external users will get a windows authentication prompt on the browser.
And of course the other way is to simply have 2 zones - one for FBA, one for windows authentication. Windows users would go to 1 url (maybe an internal url), FBA users would go to another.
