The mailing list for users of the eduroam Configuration Assistant Tool (CAT)

[Stefan Winter <stefan.winter AT restena.lu>]

Hi,

further to this: trunk code now checks for all these conditions. If you
were to execute the realm check functionality in current trunk, you'd
get the attached output.

Thanks for talking to us about things that aren't detected properly yet
- all this makes the CAT even better!

Note: I've marked the non-HTTP case an informational "*" UI element
because we don't have confirmation that it's this particular thingy that
makes the Mac Pro fail validation. If it positively is the root cause,
this would better be elevated to a warning (!) UI element.

Greetings,

Stefan Winter
