Reading these messages I have determined that since I have md5 hashed passwords in my openldap database I need to use PAP + TTLS.  I have read and performed the radtests at the top of the inner-tunnel config file with successful auths.  Specifically, I ran the following successfully:

I enter the username and password in the dialog (cisco WLC and Mac OSX Client) and get the following from the freeradius debug output.  I think its trying to do a form of authentication that I do not want hence why I am getting "No Authenticate method found for request".  Any guidance would be greatly appreciated.  If you need me to supply config files I can do that.  Thank you ahead of time for taking the time to read this:

  You edited the configuration files and broke them.  Don't do that.

  The supplicant is using TTLS with MS-CHAP inside of the TLS tunnel.
You edited the "inner-tunnel" virtual server, and deleted "mschap" from
it.  Put it back.
