Hi,
We have noticed an issue where group memberships are not being updated on a significant number of our machines.
It appears that this has been reported in the following two bug reports:
https://pagure.io/SSSD/sssd/issue/3869 https://pagure.io/SSSD/sssd/issue/3886
There hasn't been any activity on these for a few months now, so I thought I would add a me-too, and offer to do any debugging necessary.
Thanks Toby Blake School of Informatics University of Edinburgh
