Kentico has supported multiple authentication methods for a long time now. I know this capability was in the older versions like 4.0, and 5.0, heck it may have even been there since version 2.0 or 3.0. Chances are if you have been developing on Kentico for any length of time you may have been tasked with configuring Kentico to do more than just Forms based authentication. That could be in the form of some sort of custom authentication, Single Sign On (SSO) authentication, or the next most likely, Windows Active Directory for Mixed Mode based authentication.
My team and I have done this exact thing many times. Most frequently it involves enabling what is commonly referred to as mixed mode authentication. In Kentico, mixed mode authentication lets you use both Forms based authentication as well as Windows AD based authentication. Even though I have done this specific task many times there always seems to be some sort of trick required to getting it to work correctly. Today I am going to share a tip that hopefully helps out any developer who needs to configure Kentico to utilize Windows AD for Mixed Mode authentication.
