To facilitate the provisioning of access control by a
security administrator using the View-Based Access
Control Model for tables in which multiple users may
need to independently create or modify entries,
the initial index is used as an 'ownerindex'.
When used in conjunction with such a security policy
all entries in the table belonging to a particular user
(or group) will have the same value for this initial
index. For a given user's entries in a particular
table, the object identifiers for the information in
these entries will have the same subidentifiers (except
for the 'column' subidentifier) up to the end of the
encoded owner index.
