I'm desperately trying to make my WSIT client to talk to a Microsoft WCF web service using Kerberos authentication. Both the client and server machines run Windows OS and are in the same Active Directory domain. I've been able to setup the WSIT client by following the online documentation and get it to send the encrypted SOAP message with the Kerberos token to the service, but I'm getting the following error on the WCF service side when it receives and validates the token:
The key size requirements for the 'Basic128' algorithm suite are not met by the 'System.IdentityModel.Tokens.KerberosReceiverSecurityToken' token which has key size of '64'.
It seems that the WSIT client and WCF service are not using the same algorithm to generate key materials. My question is: how do I fix this? please help. Thanks.
