converting pap to chap

[Stefan Kronawithleitner]

Hello,

I have a little problem concerning proxying of pap-auths.

The existing setup is a freeradius 1.1.6, allowing auth from a NAS and 
PEAP against an eDirectory (ldap) userbase, which works fine. However, 
users of another realm should be proxied to another radius-server - 
which works fine for PEAP, but failes from the NAS, because the NAS can 
do only PAP - which is not allowed on the other radius-server.
It is not possible to make CHAP-Auth from the NAS or allow PAP on the 
other side (which is not under my control).

So far, so bad.

But theoretically it should be possible, to convert a PAP-Auth to a 
CHAP-Auth - so i did a search in the archives and found some threads of 
users with the exact same problem. There was a conversation in 2003 
between someone submitting a patch for a module and Alan DeKok - talking 
about the best solution, but there never was a conclusion - only that it 
is not possible without code modification.

I read through the changelogs, finding nothing like that - has there 
been a change? Is it possible to convert PAP to CHAP? Howto?

Thanks in advance,
Stefan
