rlm_python works in -X, fatal signal when started using systemctl (pRet is NULL)

[Jonathan Davis]

Hi Jorge,

Yes, the python script I wrote works when FreeRadius is run from the 
console in debug, I am able to use the NAS and in the debug log I see my 
authenticate method being called and the results returned. When I 
upgraded to the latest, I messed things up I believe.

Other tasks took my attention and I haven't been able to follow up or 
put work towards this until today, and hope to figure it out.

Thank you,
  Jonathan
