Hi,
[This is in continuation to Implementing Single Sign-On from .NET Application to SAP System, using SAP.NET Connector 3.0]
After hosting WCF service on IIS and accessing from client, it is giving error "Kerberos SSPI not usable with this User account". This error puzzled us.
Any help or pointer will be highly appreciated.
Markus Tolksdorf and Tim Alsop , I need your expertise again on this. 
Thanks in advance
Atul Sharma
