On SharePoint side - other than enabling Kerberos at web application level - is there any other step needed? What?

Hi there

My Network guy says that he has taken all necessary steps to roll out Kerberos.

In the scope of SharePoint - I have extended our web application and this has Kerberos enabled (instead of NTLM). <-- Other than this any more steps are needed on SharePoint side? Which ones?

Thank you so much.
