Getting started example with Username authentification sett.

[aheranney]

Hello,
I am currently trying the .NET SDK, and use the "Getting started" client.
I have 2 OPC servers to make tests: a Beckhoff and a Staubli OPC server.

Client example is working fine with Beckhoff server which is anonymous but not with the Staubli which use Username/Password authentification.

When I try to connect with the Authentification client example I get an exception certificat cannot be null (I don't know how attach an image to this post).
However I have selected and set username setting, it works with UA Expert, there is only a Username "default" no password.

Why is there a certificat problem because there is no certificat in Username/Password mode, isn't it?

Thank you
