you are right. my apologizes.
I’m trying to connect from a windows 10 machine (machine A) to another windows 10 machine (B), where privacy idea credential provider is installed successfully (I can authenticate from the console). If i want to connect from A to B, using microsoft remote desktop application, i have to type username, domain and password before click the connect button. When i click connect, the credential provider on B ask for second factor, but authentication fails everytime. After the first failed attempt, the provider ask for username, password and second factor, directly in the remote session. In this manner authetication works. It seems that rdp application from A does not provide the correct informations (username or password) to credential provider on B. When i give data directly to credential provider all goes fine.
I hope i explained it well this time.
Thank you very much
