If only one connection is available to the current user, Guacamole will automatically connect to that connection instead of providing a home screen with a connection list. This works well for normal users but causes confusion for users with admin permissions, particularly when they have just started using Guacamole and have just added their first connection.
The intent behind the automatic connection behavior is to direct the user to the part of Guacamole most relevant. With this in mind, the current behavior is not correct for administrative users who are expected to both use and maintain connections, as automatically connecting makes accessing administrative functions cumbersome.
If a user has admin permissions, they should not be automatically connected, even if only one connection is available.
