(2015-07-10) HTTP Error 400 Bad Request – Error When Accessing Claims Based Website

Posted by Jorge on 2015-07-10


Do you have a claims based website and do you get the following error when accessing the website?

Figure 1: HTTP Error 400 – Bad Request

Does the problem go away if you remove a large number of claims rules that issue a large number of claims? If yes, the issues is most likely that the "Request header too long", although it is not mentioned. When that happens, in this case, the user is not necessarily a member of too many groups. In this too many claims having generated and presented to the application. The solution is to increase the default HTTP header or packet size. See the first article on the list of articles below to understand how to solve it. However, Instead of increasing the HTTP header or packet size, see if you can optimize the claims rules to process/issue less claims!

After configuring this, reboot the server!!
