GACL - a Grid ACL manipulation library

GACL is a C library for manipulating Grid Access Control Lists, written in XML-based Access Control Languages. The aim of GACL is to insulate application authors from changes in ACL format and to provide easy access to ACL information (ie to remove the need for every application to know how to parse XML and evaluate ACL's.)

GACL has grown out of the ACL handling of SlashGrid and GridSite. SlashGrid now uses the standalone GACL library, and GridSite is being modified to support GACL ACL's. The 0.9 rewrite of GridSite applies GACL access control in an Apache module, mod_gridsite.

My talk at the May EDG security workshop at CERN has some background information and the rationale for GACL.

Current sources and RPMS of the 0.9.0 version are available from the EDG CVS and package repository, and are (still) described by the 0.1.5 Release Notes

(A recent unstable snapshot is usually also in the EDG CVS)
