RADIUS Questions

I've been running FreeRadius 2 on Centos 5.5 for a while now. So far so 
good. I'm now looking to make connecting to our WPA secured wireless easier.

The RADIUS server is running in a VM and since the system is in use I 
have copied the original and used that copy to create a test 
environment. I have run through all system updates and have upgraded all 
relevant packages. The test system is at 5.6 now.

Currently with Windows machines I can't just connect to the SSID and 
enter in a username and password. I have to go and manually add the 
SSID, modify some settings; specifically turning off validating server 
certificate, turning off automatically use my Windows login, and turning 
on User or computer authentication mode.

We also have some OS X clients. Fortunately connecting via OS X is 
easier. The catch is that I have to join the machine to our domain. 
After that it's pretty much username and password, and they are on.

Ideally I would like to have a simple "connect to this SSID, enter your 
username and password and that's it" solution and still have all 
requests checked against our Active Directory server.

On a side note. I'm going through my settings trying to get this working 
more smoothly and I ran across:

wbinfo --a user%password (yes I'm adding in my username and pass)

plaintext password authentication succeeded
challenge/response password authentication failed
error code was NT_STATUS_ACCESS_DENIED (0xc0000022)
error messsage was: winbind client not authorized to use 
winbindd_pam_auth_crap. Ensure permissions on 
/var/cache/samba/winbindd_privileged are set correctly.
Could not authenticate user MYUSERNAME with challenge/response

I know the 2 error lines are permissions related. I'm not sure what the 
permissions should be on this file/folder. Can someone let me know this?

The tutorial from FreeRadius says that I should get output similar to:

plaintext password authentication failed
error code was NT_STATUS_NO_SUCH_USER (0xc0000064)
error message was: No such user
Could not authenticate user CHSchwartz%mypassword with plaintext password


ntlm_auth --request-nt-key --domain=MYDOMAIN --username=MYUSERNAME
NT_STATUS_OK: Success (0x0)

So the Auth is working. I don't understand though why my AD server is 
letting cleartext passwords through. It shouldn't right?

Any help would be greatly appreciated.
