When users change their passwords in Horizon, the Identity service invalidates their tokens. As such, those users need to request new tokens using their new credentials.
However, in previous releases, Horizon did not automatically log users out after they changed passwords. Horizon then displayed authorization errors to these users, prompting them to log out and re-login.
With this release, Horizon will now automatically log users out if they change passwords. This forces users to request valid tokens from the Identity service immediately.
