HTTP 400 – Bad Request (Request Header too long) error

Hello SQD community,

I’ve encountered a problem with some of the users while using windows authentication (SSO):
When trying to open any SquaredUp page/Dashboard the user is getting a HTTP 400 – Bad Request (Request Header too long) error.
The root cause for this behavior is that the specific user/users are members in large amount of AD groups.

I’ve found the solution on a Microsoft KB:

DO THIS ON YOUR OWN RISK!

I’ve also published an article on the subject:

Hope it helps.
