Hi everyone,

We have shortly migrated our user database to OpenLDAP, keeping the 
UNIX-crypted passwords. Now I would like to let wireless users authenticate
against this LDAP Server. Since we do not have a PKI in place, I have 
set up an auth chain using PEAP/MSCHAPv2 (you might have guessed from my previous 
posts).
For a first push, I split the chain and tested both LDAP and PEAP with cleartext
passwords on the RADIUS side; they both work now.

The big question is, of course, how to deal with the encrypted passwords.
Any Challenge-Response protocol such as MSCHAPv2 won't quite cut it,
unless you imagine fancy stuff like passing the seed for crypt to the
client first who can then in turn do the required hash ...
So what might be a feasible Option? TTLS has been a second option only 
so far, since PEAP is already wired into Windows XP -- which is still 
what most of our users will be running for some time :-|
On the other hand, I haven't seen anything like PEAP-PAP so far, but I
have seen there is TTLS-PAP and the like.

Any suggestions?
Thanks, Martin
