Access and Authentication

After you create the data catalog, you can give users and application developers permission to shop there and find all the data they need.

Sybase Data Federation integrates with your existing directory services. If users and groups are under different administrative domains within the organization, you can integrate each local directory service that authenticates those users. A single Data Federation domain can integrate with multiple, heterogeneous directory services including LDAP-based directory services (Microsoft Active Directory, Sun ONE Directory Service) and Network Information Service (NIS) directories. Because Data Federation can integrate with multiple, heterogeneous directory services, you can associate many different users and groups with a Data Federation domain without disrupting local authentication schemes. In this way, you create a virtual pool of users and groups to whom data owners can grant access to data. And you do so without having to give remote users accounts on each local system.

Data Federation access control operates across networks, departments, and locations. For a user to have access to a specific data item, the data owner must establish the appropriate access rights for that item. The user can then browse the catalog to find the data available to him or her, and access the data as if it were local.

Consider some important implications of this unified approach:
