Is there a log of permissions changes?

We are trying to track down who or what changed "curate" permissions for a group's access to a collection. Is there some sort of log of permission settings for groups over time? We are running metabase v1.50.13.

Users log in with an sso identity provider run by another business unit. I bring this up because in the past we found out that users were being removed from a permission group due to a misspelling of the permission group name within that identity provider (azure AD). Would that be a possibility for removing curate permissions from groups as well?

There is no log for that unfortunately:

Are you elf hosting? Maybe you can get some insights from the permissions table in the application DB

Hey benlamb

As Tony mention, not an easy way and there's no report we have in our analytics collections at the moment.
If you're self-hosting you can cross reference with a couple tables in your application database.

permissions_revision
collection_permission_graph_revision

Thanks.

Thanks for the pointers!
