Realm parsing and \r => =0D

[Rich Graves]

I found the documentation of what needs to be done to support both NTDOMAIN\ and @realm styles in the same vhost. In sites-available/inner-tunnel, it says:

        #  If you are using multiple kinds of realms, you probably
        #  want to set "ignore_null = yes" for all of them.
        #  Otherwise, when the first style of realm doesn't match,
        #  the other styles won't be checked.

What this fails to say is where ignore_null needs to be set. Despite the comments to the effect that modules/suffix is deprecated and no longer used by freeradius 2, editing modules/suffix appears to work. Is there a non-deprecated fix?
