Can we somehow configure what permission these directories created with? (BTW the file in there are still 755, so its just the directory that blocks other users.) Or is there an "official" solution for getting these logs like the fetching tools for system and user logs?

1) 8.1.5 / 8.0.7 will have a knob to manage directory permissions for these directories.
2) You can use condor_tail to access logfiles from a running job as a user.
