    DESCRIPTION

       "To facilitate the provisioning of access control by a

       security administrator using the View-Based Access

       Control Model (RFC 2575, VACM) for tables in which

       multiple users may need to create or

       modify entries independently, the initial index is used

       as an 'owner index'.  Such an initial index has a syntax

       of SnmpAdminString and can thus be trivially mapped to a

       securityName or groupName defined in VACM, in

       accordance with a security policy.

       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.

       To configure VACM to permit access to this portion of the

       table, one would create vacmViewTreeFamilyTable entries

       with the value of vacmViewTreeFamilySubtree including

       the owner index portion, and vacmViewTreeFamilyMask

       'wildcarding' the column subidentifier.  More elaborate
