Hello Thomas,
This bug has been recently fixed but it will require you patching your installation.
Download the file at [this link](https://jenkins.gluu.org/maven/org/gluu/super-gluu-radius-server/4.4.0.Final/super-gluu-radius-server-4.4.0.Final.jar). Then replace the file `/opt/gluu/radius/super-gluu-radius-server.jar` with it. Make sure it has the
same file name as the old file , i.e. `super-gluu-radius-server.jar`.
Restart radius with `service gluu-radius stop` then `service gluu-radius start`.
That should do it.
