how to ensure that our site authenticates with kerberos

Question

I am working with HttpWebRequest in dotnet. I am using delegation (impersonation) to do this, request.Credentials = CredentialCache.DefaultCredentials;
request.ImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Delegation;

in webconfig file

identity impersonate="true"

for Impersonation Kerberos is required... So i need to ensure wether the site authenticates using kerberos or NTLM because my code throws 401 unauthorized error

so please help me in this!!!!!!!!!!!!!!!!!

Answer 1

Is the account you are impersonating trusted for delegation in the AD?
