Re: [HTCondor-users] python bindings/bdii problem

Hi Stephen,

The CE collector/schedd (presumably the one on 9619) should have very 
open ALLOW_READ policies by default. I would set `COLLECTOR_DEBUG = 
D_CAT D_ALWAYS:2 D_SECURITY` and that should tell us more about why auth 
is failing.

Thanks,
Brian
