Guacamole Auth HTTP

This modules will proxy your HTTP Auth Request to a provider of your choice

Building

Get the Simple JSON for Java and then add it to the Guacamole CLASSPATH You can copy, symlink or adjust Tomcat{6,7,8} configurations

apt-get install libjson-simple-java
emerge dev-java/json-simple

You will need also org.apache.commons classes (to be documented)

From the guacamole-client root clone this project into extensions/

cd extensions/
git clone THIS
cd guacamole-auth-http
mvn package
cp target/guacamole-auth-http-2014.38.jar /var/lib/tomcat7/webapps/guacamole/WEB-INF/lib/
cp /usr/share/java/json-simple-1.1.1.jar /var/lib/tomcat7/webapps/guacamole/WEB-INF/lib/

/etc/init.d/tomcat7 restart

Configuration

Add the following to your guacamole.properties (/etc/guacamole or /usr/share/tomcat7/.guacamole/guacamole.properties)

auth-provider com.edoceo.guacamole.auth.HttpAuthenticationProvider
auth-http-page: http://sso.example.com/external/guacamole
auth-http-head-auth: Whatever Here is added as Authorization header and is required

HTTP Auth Server

The HTTP Server will be sent

POST /external/guacamole HTTP/1.1
Accept: application/json
Authorization:  Whatever Here is added as Authorization header and is required
Content-Length: 47
Content-Type: application/json

{
	"username":"something",
	"password":"something"
}

The HTTP Server should respond with proper HTTP codes: 200, 403. The responding JSON looks like for a VNC:

{
	"protocol": "vnc",
	"name": "Connection Name",
	"hostname": "vnc.example.com",
	"port": 5900
}

For RDP you can use (NOTE: host vs hostname parameter changed with last commit):

{
	"protocol": "rdp",
	"name": "Connection Name",
	"hostname": "vnc.example.com",
	"port": 3389,
	"username": "user@domain.local",
	"password": "AlocaP4ww0rd",
	"server-layout": "fr-fr-azerty"
}

Notice that ALL field are required for RDP / VNC, the auth module can throw exception if some is missing !
