HYBRID ACCESS CONTROL MODEL IN COMPUTER SYSTEMS

Techniques for providing hybrid access control in a cloud-services computing environment are provided. In one embodiment, a method for providing hybrid access control is provided at a host computing device. The method includes obtaining access control settings including at least a first user's role-based access settings with respect to a first sub-system of a hierarchical computing-resource system. The method further includes propagating the access control settings from the first sub-system to a second sub-system; obtaining user group domains assigned to a plurality of sub-systems; and obtaining a group membership associated with the first user. The method further includes determining, based on the obtained user group domains and the obtained group membership associated with the first user, whether the first user's role-based access settings propagated to the second sub-system are to be adjusted; and making adjustments accordingly.
