Hi, from the Guacamole manual, chapter 5
""" Authentication and security RDP provides authentication through the use of a username, password, and optional domain. Most RDP servers will provide a graphical login if the username, password, and domain parameters are omitted. One notable exception to this is Network Level Authentication, or NLA, which performs all authentication outside of a desktop session, and thus in the absence of a graphical interface. If your server requires NLA, you will need to manually choose this as your security mode, and you must provide a username and password. """ As far as I see providing username and password is only possible when configuring the connection(!), so all users who are allowed to use this connection with authenticate with the same username and password, a security issue I think. Or you configure a special connection for each host/user. But this means, the connection has to be reconfigured if the user changes his password. -- View this message in context: http://apache-guacamole-incubating-users.2363388.n4.nabble.com/RDP-connection-problems-with-Windows-Server-2008-R2-No-NLA-tp34p66.html Sent from the Apache Guacamole (incubating) - Users mailing list archive at Nabble.com.
