Authentication With Directory Connector User using .NET SDK

[#1]

I am using .NET SDK to authenticate my user on qlik sense this way:

location.AsNtlmUserViaProxy(proxyUsesSsl: false, loginCredentials: new System.Net.NetworkCredential(_qlikUsername, password));

Now I have created an ODBC user directory connector in qlik sense to sync users from a database.

What I need to achieve is the following:

- Fetch these synced users from qlik sense

- Use a user from them for authentication

- Making this authentication without password as what I expect is only user identification.

I am using .NET SDK 3.0.2
