ok. my script returns "Accept" and "Reject" and it works without any 
problems. but is it okay to use it this way to authenticate users with 
an external script? are there any drawbacks using it this way and not 
using the script/exec module?

i also found some hints about rlm_python and as my script is written in 
python it may be a good idea using rlm_python. are there any benefits, 
beneath better performance, using rlm_python?
