Description
This error can occur if delegation is not enabled on the service account used for Kerberos.
This is not a fatal error (i.e prevents log in to the Spotfire server)
Resolution
On a domain controller, start the Active Directory Users and Groups applet and make sure the delegation is enabled on the service account used for Spotfire server.
Please see here to learn how to enable delegation.
To confirm this, from a users workstation check the user ticket with klist as shown below. Look at the ticket that corresponds to a spotfire login. The ok_as_delegate flag will not be present.
