I'm trying to connect to a REST service with an AD authentication. I am using this connection for the login process for my app but the problem is that it is only using the first credential. I mean, if the first user make a login always works fine but, if later another one try to make another login with other credentials, the webrequest always send the petition with the first credentials, not with the other ones.
I also have tested this code on my desktop app and it does work fine so i would like to know if there is any kind of problem with xamarin or, on the other hand, if anyone have an idea about how to solve my problem.
PD: I´m using xamarin forms for an android app
