'Attribute "User-Password" is required for authentication.' (EAP/TTLS/RADIUS/PAM)

As far as I understand your config files, you want to use MD5.

So the question are:
- is the client really sending MD5 hashes (or is it sending NT hashes  
for example)
- can PAM handle it?
- has PAM access to the password in MD5 or in clear to be able to  
check against it?

I hope that my hints could bring you forward.

Have  a nice day!

PS.: personally what I find curious is that there is no "ttls" in the  
log, except at initialization of radiusd.
