Token Authorization

[krzychk2]

Hi,

I'm a new user in freeRADIUS. 

I'd like to do a solution like token authentication.

Firts step.
User is authorized by user/password. 

Secound step:
For the authentication from LDAP is taken further informations (like UID, date of birth) and user is asked about it.

I think it is something familiar with CHAP Challenge but I don't know how to combine this solutions.

Could somebody help me??
