I have a freeradius server configured to do both EAP-TLS and LDAP auth. It
works great so far. If I have a cert. configured, then I'm authenticated
with the cert. If I don't have a cert then I get prompted for my un/pw on
my NAS's Captive Portal page, which then passes my username/password on to
the Radius server which then checks my LDAP server if my un/pw are correct.
When I look through the debug logs, however, I see that the rlm_ldap module
is doing an LDAP search for my username during each stage of the EAP
session. Is there a way to configure freeradius so that it won't try LDAP
auth in the middle of an EAP session?
