Display ADFS 2.0 Forms Authentication Login Page Instead of Windows Authentication Prompt

After installing ADFS 2.0 for SharePoint a Windows login prompt was shown when the SharePoint site forwarded to the ADFS server instead of the ADFS Forms Authentication login screen. 



No matter what account I tried to use here I would eventually receive a 401 Not Auhorized error.




The reason for this is that the ADFS website tries to use Windows Authentication before trying to use the Forms authentication which displays the loging page below.


Forms Login Screen for ADFS 2.0


To fix this do the following on the ADFS server:

1. Open IIS and Explore under Default Website\adfs\ls


2. Open the web.config file with Notepad, look for the localAuthenticationTypes section.



3. Move the line for Forms above the line for Integrated and save the web.config file.  This will force the ADFS application to use the Login Page authentication before trying to use Windows Authentication.

    Thanks for posting this - it fixed exactly the problem I was having in being able to show the difference between form-based authn and IWA.

    But now users that could use SSO with Windows Auth. get the Forms login too.

    This is no solution to mix.

    This is set in the web.config, the wsFederation node: authenticationType.

    Thanks for the info! Never thought about the XML order being relavent.

    I was actually having the inverse issue where internal users would get Integrated Auth and external would have Forms from the ADFS Proxy. Moving the basic before the forms on the Proxy gives them a similar experience.

    Thanks!

    Hi Richard,

    Is it possible for adfs server to use Forms authentication or we have to take adfs server proxy for Forms Authentication ?

    Thanks in advance

    The client can undoubtedly make the "entertaining" sends, letters advances and pamphlets, ie. the immaterial stuff, available by means of semi-login. hotmail sign in

    He can't get to different sends or change any record data. The client can choose what all things can be gotten to and changed when in semi login. hotmail

Add User As Local Administrator On Domain Controller

I recently was settting up a new Microsoft SharePoint 2010 machine and had promoted the machine to a domain controller before creating my SharePoint admin accounts.  I needed to add several of my accounts to the local Administrators group.  Unfortunately after you promote a server to a domain controller you can no longer access the GUI for Local Users and Groups.  Instead I had to use the command line to add the users. Open a command promt using the "Run as administrator" function and then run the following command. net localgroup Administrators /add {domain}\{user} Note: do not include the {} brackets.

Horizontally Scroll A Large Power Apps Gallery

Image
So you have a lot of data to display but the screen in Power Apps isn’t large enough. My friend Ronald Sease recently showed me how to create a gallery in Power Apps that you can scroll horizontally. It’s a simple but powerful solution utilizing a horizontal container and a vertical gallery. Demo Instructions First add a Horizontal container to your screen. Set the LayoutOverflowX property on the Horizontal container. LayoutOverflowX = LayoutOverflow.Scroll Add a Vertical gallery within the horizonal container you created. Set the following properties on the Vertical gallery. ShowNavigation = true (this isn’t required but the navigation buttons make it much easier to move up and down the list when the up/down scrollbar is off the screen.) Height = Parent.Height (if you are using the Show Navigation option then set this to Parent.Heigh - 20 so that the navigation buttons are not covered up by the scroll bar.) LayoutMinWidth = 1000 (This value needs to be larger th
