802.1x and LDAP

I am extremely green to both 802.1x and radius and am trying to set  
this system up quickly as students arrive on campus in a couple of  
weeks so please forgive me if I ask questions that have been answered  
or exist in the documentation.

I need to authenticate windows and osx wireless users using Cisco  
AP's to the freeradius server using our OSX ldap directory as the  

I can use radtest from another host and authenticate an LDAP user via  
the freeradius server and get an Access-Accept packet from the server.

When I attempt to connect via a windows or osx client to the AP I get  
error messages about User-Password being required and the Access- 
Request packet does not have the User-Password attribute.

Many of the settings are the default. The settings I have changed  
have been from several online tutorials none of which talked about  
both 802.1x and LDAP.

I'm embarrassed not to have read all the documentation but I'm really  
in a time pinch here. Again I beg your indulgence.
