Arran is probably referring to that with EAP TLS reauth you are actually
using the authentication (and possibly authorisation) credentials from
a previous session that can even be a few days prior.
You might decide to do some user focused authorisation in the post-auth
section[1], for example you might reject a user if their user account
has been disabled, or if they are in the wrong group or maybe they have
been a Bad Bad Boy(tm) :)
You might then have them marked 'disabled' in your LDAP tree however the
EAP-TLS reauth bit never gets that far....so you end up accepting them.
Again, another reason not to do user based authorisation. :)
Cheers
[1] or indirectly in the authentication section via an amended LDAP
filter where you only authenticate against user objects where
'accountdisabled=false' or something
