Hi Alan,

That same wiki says 'The ldap module can only work with PAP passwords since
it needs to send the clear text user password to the LDAP server to
authenticate the user.' I might be mis-understanding as im new to Radius,
but that doesnt sound to positive. Anyway... I'm hoping to find a workaround

So I checked my sites-enabled/default and it does have the LDAP module
(I striped out the comments and highlighted the bits I changed)
authorize {
#       auth_log
#       wimax
#       IPASS
        eap {
                ok = return
#       unix
*#       files*
#       sql
#       etc_smbpasswd
*        ldap*
#       daily
#       checkval

#       Autz-Type Status-Server {
#       }

authenticate {
        Auth-Type PAP {
        Auth-Type CHAP {
        Auth-Type MS-CHAP {
#       pam
*        Auth-Type LDAP {*
*                ldap*
*        }*
 Allow EAP authentication.
#       Auth-Type eap {
#               eap {
#                       handled = 1
#               }
#               if (handled && (Response-Packet-Type == Access-Challenge)) {
#                       attr_filter.access_challenge.post-auth
#               }
#       }

In addition here is the output of my debug:
