Hello, I have a perl module that changes the username during the authorization phase (retrieve from a oracle database) by modifying the user-name attribute in the RAD_REQUEST dictionary. This update is global and can be used by the authentication phase (still handled by the perl script). I try to switch from perl to python as i'm more comfortable. Everything is ok except i don't know how to modify on the fly the user-name. in the 'authorize(p)' function, p is the read only tuple of the request. I cannot update the request here. The return of the function is (RLM_MODULE_something, tuple4reply, tuple4config). I still cannot change here. Moreover, if i change the tuple config in the authorize function , how i can retrieve it in the authentication function? Maybe i miss something as i'm a beginner on FR. Regards, Laurent
