LDAP authorization for EAP-TLS authentication

16 Mar 2006

      I'm trying to understand the relationship between the modules in the  
authorize {} and authenticate {} sections and how it relates to the  
directives defined in users.  EAP-TLS works fine, but I can't seem to  
figure how to get make the ldap authorization reject a user.

DEFAULT Auth-Type := eap, Autz-Type := ldap

authorize{
	preprocess
	ldap
         eap
}

authenticate {
	eap
}

ldap {
	server = "our-server.itc.virginia.edu"
	identity = "uid=uva-all,ou=ITC-User,ou=It,o=University of  
Virginia,c=US"
	password = "our-password"
	basedn = "o=University of Virginia,c=US"
	filter = "(wirelessAccess=%{Stripped-User-Name:-%{User-Name}})"
	base_filter = "(objectclass=Person)"
	start_tls = no
	access_attr = "wirelessAccess"
	ldap_connections_number = 5
	timeout = 4
	timelimit = 3
	net_timeout = 1
	access_attr_used_for_allow = yes
}

In the ldap server logs show multiple queries, which are not  
returning anything.
This can be confirmed with:
ldapsearch -b "o=University of Virginia,c=US" wirelessAccess=kmm6b  
wirelessAccess
which returns nothing.  If nothing is returned shouldn't the  
authorization fail?  I'm missing something, hopefully not too obvious...
