hi: I know why. I didn't understand the whole procedure. I should set up attribute "Simultaneous-Use" so freeradius would call checksimul. so I setup below at "default" site "authorize" section: update control { Simultaneous-Use := 1 } and now my check code runs fine. but the result is still bad: 1. the checksimul code runs after authentication. I would prefer not doing authentication at all if I already know this login is invalid. if possible checksimul should run before authentication. 2. although checksimul return "RLM_MODULE_REJECT", nas still get "Access-Accept" (which comes from success authentication). I have found similar report at email list. I guest I need to change some internal variable so freeradius know it is now "Access-Reject". if checksimul runs after authentication by design, I think my best place to put the checking code is at "authorize" section. but in one EAP connection, the "authorize" section runs many times, which means my checking code runs many times. may I ask what is the best method to let the module runs only once at "authorize" section?

hi: I am using freeradius 3.0.4 comes with rhel 7.1. I want to write a checksimul perl script. but it seems won't be called. I create a rlm_perl instance "check_login", and put it under "default" site:

session { check_login }

and at perl script I write my code at finction below:

sub checksimul { &radiusd::radlog(L_INFO, "check_login: I am here"); return RLM_MODULE_OK; }

but "radiusd -X" show my code is not be called after user authentication. the code works fine if I put it at "authroize" or "post-auth" section. I don't know if I miss some steps or I met a bug..
