after making changes to a policy attached to a user's authorisation with RBAC, should that user have to re-auth for them to take effect? and/or, what's the error in this policy here to block the user from accessing the files (which they can do, see on the right)

Hi @Robin Moffatt, the user shouldn’t re-auth, it might take a few seconds to take effect due to the fact it’s cached. The resource should be by this pattern:
arn:lakefs:fs:::repository/{repositoryId}/object/{objectKey}
Replacing the first
*
with
object
should do the job

ah, so literally
object
?
I saw that in the docs but thought it was a placeholder for the path

Yes, in order to check it try reading or writing to the path

so with
Copy code
arn:lakefs:fs:::repository/drones03/object/sensitive/*
I can still browse and see the folder contents, but if I click on the object I get an error. Is the error showing the permissions are working? I'd have expected not to be able to browse the contents either

I understand, currently, listing can be restricted only by the repository level

ah ok, good to know
and that error I'm seeing there is the one saying "access forbidden"?
thanks for all your help btw 🙂

No problem 😃
and that error I’m seeing there is the one saying “access forbidden”?
It is, but I agree the error isn’t clear would you like to open an issue for that, or would you like me to?

We're a lot like s3. IAM there also has a bucket-level permission for listing buckets. https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListObjects.html says:
To use this action in an AWS Identity and Access Management (IAM) policy, you must have permissions to perform the s3:ListBucket action.
It's an object store thing: there really are no directories!

OK. So would it be valid to log an enhancement request to be able to limit the listing of a given object path [folder] ? If I'm understanding correctly the granularity by which access can be blocked is per object for RW but only per repo for list?
