A user accesses a remote session, the connection to which is managed by a connection broker, according to a single sign-on (SSO) process. The SSO process includes the user entering his or her credentials and being authenticated to the connection broker. In addition to user authentication, the SSO process includes connection broker authentication to confirm that the connection broker is trustworthy. When the connection broker is authenticated, the user credentials are transmitted to the connection broker in a secure manner and the connection broker forwards them onto a machine hosting the remote session so that the user can be logged into the remote session without entering his or her credentials again.
