To integrate resources that use Unix-like semantics for user management and access control in a grid environment, authentication, site-local authorization and credential mapping are required. The Site Access Control suite, comprising LCAS, LCMAPS, SCAS and gLExec, provides the mechanisms to implement authorization decisions and to make (and enforce) a mapping from grid credentials to the Unix world. It can also provide authentication and credential validation capability for those systems that don’t have built-in TLS handshakes.
If you have any trouble in using this Site Access Control suite, please contact the product team by email at grid-mw-security, at the domain nikhef.nl.
