Hello Joël,

I've adjusted some paths and other little things.     Freeradius is up     smsotpd is up I've populated the berkeley db with my identifiant

don't use the smsotpd, use the rlm_perl which is a complete different setup. The mininimal config you find in the README in the corresponding directory.

Use of uninitialized value $type in hash element at ./pap_challenge_request.pl line 51.

this happens, when you have a way to old Authen::Radius module. On which distribution are you?

Additionaly  i suppose that i will need to change values regarding my corporate active directory. Could you point me out where it's needed ?

No, rlm_perl expects the username already writen as username@REALM.

it is possible to test the first stage "krb5" with radtest ? huh !! I think it could be possible to answer to this question by myself .. ;o)

Yes, it is. See the rlm_perl/README file. Cheers, Thomas
