Subject RE: CAS Authentication problem
Date Fri, 31 Aug 2018 18:55:54 GMT
Misprint on the .tar.gz.  Should be just .tar.
So excited to get this working.

The solution was to follow the action item sent resulting in the following configuration:

The CAS Authentication directives in $GUACAMOLE_HOME/

From the Guacamole Manual, Chapter 6. Database authentication section mysql/  the jar files
for /extensions and /lib have been added.

In $GUACAMOLE_HOME/extensions there are two jar files
-rw-r--r-- 1 root tomcat  930509 Aug 28 18:27 guacamole-auth-cas-0.9.14.jar
-rw-r--r-- 1 root root   3968839 Aug 29 17:51 guacamole-auth-jdbc-mysql-0.9.14.jar

In $GUACAMOLE_HOME/lib there is one jar file
-rw-r--r-- 1 root tomcat  999635 Aug 28 18:28 mysql-connector-java-5.1.44-bin.jar

Some testing steps:
With the guacamole-auth-jdbc-mysql-0.9.14.jar only Guacamole was reachable but the user (guacadmin)
had no privileges, existing Connections were not showing up.

With the guacamole-auth-jdbc-mysql-0.9.14.jar and guacamole-auth-jdbc-mysql-0.9.14.jar the
500 (Internal Server Error) occurred with a deadly crash.

From the tomcat catalina log
SEVERE: Mapped exception to response: 500 (Internal Server Error)

From file localhost_access_log.2018-08-30.txt
"POST /guacamole/api/tokens HTTP/1.1" 500 185

Note that the redirect was attempted, show in the localhost_access_log.2018-08-30.txt
"POST /guacamole HTTP/1.1" 302

3 the solution
Add the mysql-connector-java-5.1.44-bin.jar to $GUACAMOLE_HOME/lib
(just like Chapter 6 told me to do!)

Thanks so much
Getting a task done on a Friday is so sweet!

I added  guacamole-auth-jdbc-mysql-0.9.14.jar to $GUACAMOLE_HOME/extensions.
Now have two .jar files guacamole-auth-cas-0.9.14.tar.gz and guacamole-auth-jdbc-mysql-0.9.14.jar.

You'll want to unpack the tar.gz file so that you have a JAR, but that's the correct one.

Sounds like maybe you got all of it working - what did it turn out to be?
