I've just upgraded my Pipeline Pilot 23.1 to 24.1 . Everything seems to have gone fine apart form the user login to the client when using a domain account. With the same domain account, I can sign in to server home page and download the new client but when I try and log in on the client I get 

"Unable to login to server X as user Y. You do not have permission to connect to the Pipeline Pilot server from this client. Contact your administrator for permission" 

It seems strange that I can log in on the server homepage but not the client.

The client works fine using local accounts. This has been tested using the client on both the server itself (using full server name and local host) and on a remote system. Everything was behaving as expected on 23.1 before the upgrade. 

Has anyone else had similar and found a solution?

Thanks
