Using the value of the acctsessionid column in the radacct table worked.
Here's the attributes I used.
User-Name=0021ccbea13f
Acct-Session-ID=8O2.1x819e0122000d26f7
Output of radclient:
[root@PacketFence-ZEN-6-0-0 ~]# cat radcl | radclient -c1 -r1 -x
172.22.0.201:3799 disconnect <redacted>
Sent Disconnect-Request Id 236 from 0.0.0.0:35766 to 172.22.0.201:3799

User-Name = "0021ccbea13f"
Acct-Session-Id = "8O2.1x819e0122000d26f7"
Received Disconnect-ACK Id 236 from 172.22.0.201:3799 to 0.0.0.0:0 length 20
Output of radsniff:

Successfully removed the port from the vlan and reset the auth status on
the switch.

Thanks for the help Louis. Let me know if you need anymore information to
create the patch.

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
