Cannot login to SSLVPN server in Enterprise or Kiosk mode when multiple roles assigned to authenticated user

Customer had SSLVPN server configured and users trying to access it in Enterprise mode. Most users were able to connect and work fine but some users could never get 'connected'. No error message was reported on the SSLVPN portal page. After comparing working and non working users, we realised that the non working users had a large amount of roles associated with them. The novell-openvpn.log file on the server showed the following entry when the user failed to connect:

We never get the user authentication to succeed as one would expect below (this is what follows in a setup where all works fine)
