CS_OID structures store object identifiers.
An Object Identifier (OID) is an encoded character string that provides a machine- and network-independent method of uniquely identifying objects in a distributed environment. An OID functions as a symbolic global name that means the same to all applications in a distributed environment.
Sybase uses OIDs to represent the following:
Directory objects.
Attribute types within a directory object.
Security mechanisms that assure secure client/server connections. A security mechanism may have a different local name on the client machine than on the server machine. To avoid confusion, an OID is used as a global name that identifies the security mechanism for both the client and the server. See “Choosing a network security mechanism” for a description of how a security mechanism is associated with a connection.
