Good day, I need to get the user who is opening the url of the published site, example: the published site is in the following route: 10.11.15.76:81, when the user from his team opens any browser and places the url indicated, the site should start to load, without presenting a login screen, that is, the system must identify who is the user that is accessing and based on it load the options to which he has permission, someone knows how I can achieve this ? is the implementation of a single sign on.
