FIM Service to delegate to the FIM Service? KCD config question

Hi,

Looking at this article around Kerberos config for FIM Portal, and just wondering whether the last KCD step is correct, as this does not make sense, and when I do it, the FIM Service does not start:

Step in question:

• Open ADUC and locate the service account for the FIM Service (sa_fimsvc)
• Open the properties of sa_fimsvc and choose the delegation tab
• Check Trust this user for delegation to the specified services only

Thanks
