Pablo,
When using cas protocol for login, it is possible to include the host name
(foobar1 in your case) to the ST. It escapes my how to set this, since my local
does not do this but our prod servers do. This is handy when you have multiple
cas servers.
The other form of the ST is probably for
i have property:
cas.host.name=foobar1
Looking at my postgres_jpa_ticket_entity table, I do see some services
tickets appended with this value and the format looks like to alphanumberic
formatted ticket (ST-ABC123-foobar1)
But I am also seeing some service tickets without the foobar1 appended
