General setup of FreeRADIUS with 3COM SuperStack® 4 Switch 5500G-EI

Hello,

I am currently trying to establish a setup of a FreeRADIUS-Server together with an  3COM SuperStack® 4 Switch 5500G-EI Switch. I want to try to configure multiple things to check the capabilities of RADIUS, for example SSH Authentication to the switch with RADIUS or Port Based Network Access Control with 802.1x. 

First thing, my RADIUS-Server. It is FreeRADIUS 3.0.13 on CentOS Linux release 7.5.1804 (Core). As management interface I am using Daloradius version 0.9-9. I think my radius setup is fine so far, I added some clients and users and tested the connection with the NTRadPing Test Utility (https://www.novell.com/coolsolutions/tools/14377.html):

My RADIUS debug output prints me the following when I send an authentication request (A screenshot should be attached to this post): 

(0) Sent Access-Accept Id 4 from 10.1.22.135:1812 to 10.1.100.103:63899 length 0
(0) Finished request

So, looks like it is working.

Now my problem is, how do I configure the switch? I have read multiple sections from the official documentation (http://h20628.www2.hp.com/km-ext/kmcsdirect/emr_na-c02583472-1.pdf). I have tried to apply the sample configurations like the one from page 267 without success. 

If I go through the steps like mentioned in the documentation and activate 802.x1 on a port, the device on that port just has no access to the network anymore. Sounds reasonable as I should have to authenticate first, If I try that with NTRadPing Test Utility, nothing ever reaches my RADIUS server.

I have created users, I have created radius schemes and domains and linked them. I created ACLs if they were needed for the configuration examples, but never my RADIUS-Server got any request from the switch.

I will post some configuration information below for the case that someone wants to have a look.
