What are the types of access control provided by SRB/MCAT?
SRB supports two types of access control. The first type is similar to Unix-type access control. In this type, the owner can provide read, write and all access to other users or user groups at the level of individual data objects and collections. Unlike Unix, one can control access to as many users as needed and as many groups as needed. The second type of access control is controlled through tickets. Tickets are issued by owners of a data object (or collection) to other users, groups and everyone. One can use these tickets to access data objects that they control. A ticket user need not be a registered SRB user. There are APIs and Scommands that can permit non-registered users to access ticketed data objects.
