We introduce gPLAZMA (grid-aware PLuggable AuthoriZation MAnagement)
Architecture. Our work is motivated by a need for fine-grain security
(Role Based Access Control or RBAC) in Storage Systems, and utilizes
VOMS extended X.509 certificate specification for defining extra
attributes (FQANs), based on RFC 3281. Our implementation, the gPLAZMA
module for dCache, introduces Storage Authorization Callouts for SRM
and GridFTP. It allows using different authorization mechanisms
simultaneously, fine-tuned with switches and priorities of mechanisms.
Of the four mechanisms currently supported, one is an integration with
RBAC services in the OSG Privilege Project, others are built-in as a
lightweight suite of services (gPLAZMAlite Services Suite) including
the legacy dcache.kpwd file, as well as the popular grid-mapfile,
augmented with a gPLAZMAlite specific RBAC mechanism. Based on our
current work, we also outline a future potential towards authorization
for storage quotas. This work was undertaken as a collaboration
between PPDG Common, OSG Privilege project, and the SRM-dCache groups
