Hi,

our client wish to use their Azure AD to login to Umbraco so we integrated that and at first it seems to work fine. But some users can't login, they get a message like: Bad request - Request Too Long

It seems to be on the Umbraco end, not the Microsoft login page.

Has anyone experienced this problem and found a solution?

When I googled this I found a few "solutions" where they said that the user should clear their cookies. This is not a working solution for my client.

Thanks in advance, Josef
