NetTcpBinding across Domains

Question

I am new to all this, so I don`t even know what questions I should be asking.

• I have a WCF service on Domain A.
• It will be called from Domain B.
• Domain B is not trusted by Domain A.

I'm pretty sure my clientCredentialType can not be "windows".

How do I get them to talk, and authenticate with one another?

Answer 1

You are correct that Net Tcp binding with windows authentication will not work between domains that do not trust each other.

You have atleast 2 choices:

• username and password in message header
• a preinstalled certificate
