What value should the servicePrincipalName have?

Question

I'm trying to set up client impersonation on my service.

I need to set a value for the servicePrincipalName of my services endPoint

I'm looking at this MSDN article but still cannot quite figure it out

My service is hosted in a console app on a server that we'll call ServerName1.
The Uri is: net.tcp://ServerName1:9990/TestService1/.

What specifically should my servicePrincipalName be?

I tried, with no joy:

<identity>
    <servicePrincipalName value="ServerName1" />
</identity>

Configuring servicePrincipleName is a difficult topic to describe it in a few words Perhaps these articles will help:

• Overriding the Identity of a Service for Authentication
• Security in Windows Communication Foundation

Most probably, you need to configure it the following way

<identity>
    <servicePrincipalName value="HOST/ServerName1:9990" />
</identity>

We usually use userPrincipalName instead of servicePrincipalName, like this

<identity>
  <userPrincipalName value="[email protected]" />
</identity>
