Comment 24 for bug 1723350

Maybe start with 6. From https://docs.pagure.org/SSSD.sssd/users/troubleshooting.html:
"""
To enable debugging persistently across SSSD service restarts, put the directive debug_level=N, where N typically stands for a number between 1 and 10 into the particular section. Levels up to 3 should log mostly failures (although we haven’t really been consistent especially earlier in the SSSD development) and anything above level 8 provides a large number of log messages. Level 6 might be a good starting point for debugging problems.
