HAProxy remove kerberos parameters

Hello,

I’ve setup Microsoft Exchange to use kerberos authentication behind an ADFS server but when ADFS hands off the client to Exchange there is an added parameter for ‘authToken’ that I would like to remove.

My understanding is that it can be removed, but I have failed to get any useable configuration for this.

Here is an example of the what is returned to the client:

https://mail.mydomain.com/owa/?authToken=pxj3ks2ER35350beFGD3g3D

I would like to remove the ‘?authToken=pxj3ks2ER35350beFGD3g3D’ portion here.

Thanks in advance!
