Hello Experts,

Can I limit a user to access a bucket so that he/she can only use that particular object storage bucket and create objects?

I am aware about policies defined at group level and they work just fine. However, I would like to know if I can further control access of users and have a 1:1 mapping between user and a bucket to avoid users accessing bucket object that belong to same group.

 

Regards,
