when creating a new web login on clearpass guest 6.1 (not sure about before) the pre-auth check is enabled by default, is there any good reason to use it when you are doing simple guest access from an Aruba controller?
i was a bit dissapointed by the clearpass guest user guide, 6.1 is better then 6.0 which seems to skip the web login all together (only bits and pieces can be found) but both don't explain the use of pre-auth check.
