+Guacamole makes RDP or VNC desktops available via html5 inside EGroupware.
+EGroupware supplies account information, authentication via OpenID Connect
+and allows to manage connections.
+
+#### EGroupware Guacamole app does the following:
+
+* Installs all tables (or views) for Apache Guacamole
+* Everything account-related is a view, not a table
+* EGroupware UI to create connections (Admin >> Guacamole >> Connections)
+* One has to use EGroupware to assign permissions to connections
+* Guacamole UI can be used to set advanced connection options
+
+> The app requires accounts stored in SQL. A workaround for using LDAP or ActiveDirectory for account storage (not just authentication), is to regulary use setup to migrate users and groups to SQL.
