Solution what we came up:
Each url assosiated with new auth server, but each auth server points to the same back end server. So if needs to login more that once, he uses different url, but atleast he does not have to use different user name
Did you ever get a resoluton for this? Was the feature included in 6.4? I would really like to be able to have multiple logins with the same id. I expect this to use a license - I am not trying to avoid the licensing, but this would be a useful finction for me.
One way (which makes some troubleshooting / tracking users more difficult) is to set up the main authentication to be Anonymous Server and set what your current auth server is (Radius, AD, LDAP, etc) to be an Additional Authentication Server (checking End session if authentication against this server fails).
-If you look at connected users you will then see AnonymousUser### though
