Hi Ryan
Thank you for the reply. I suspected the same issue, and indeed the 401 error is in the client log as well.
I have verified, and the Managed Account gets pushed down to my client correctly.
I have triple checked the setup of the managed account, and have set it up exactly the same way as per the documentation you linked, still exactly the same issue.
The only other place I think the issue may be, is on my Domino SSO it self.
I have internet sites enabled, and a lot of them running. I have one Global LtpaToken, running on all the Internet sites, and single sign on works perfectly. So I am lost.
