I would really appreciate if anybody could guide me to achieve this requirement. A user has told me recently that in his company, the technology team has developed a desktop app whose main purpose is to connect with salesforce using a Button. This app is just allowed for certain users with specific roles and profiles. They want this users to be able to login in salesforce automatically using the passwords they use in the company network (I assume the same active directory credentials), avoiding the login step, just to have the automatic authentication with salesforce and start to work.
Thanks a lot for your ideas, opinions, related tools or processes I could implement.
