Extended permissions are stored in the r_accessor_xpermit attribute. The value of this attribute is an integer that has been converted from a 4-byte binary number to a decimal number.

- The first 16 bits (two bytes) represent the basic permissions for backward compatibility. 
- The first 16 bits uses 0 to indicate that the permission is on 
- The second 16 bits (two bytes) uses 1 to indicate that the permission is on 
- The bit locations of the permissions are

_execute_proc = 1, 
_change_location = 2, 
_change_state = 17, 
_change_permit = 18, 
_change_owner = 19

Example:

If you issue this query:

SELECT r_object_id, object_name, r_accessor_name, r_accessor_xpermit FROM dm_acl

In r_accessor_xpermit, you may find a large number (i.e 458752) . This number is a decimal number if you change it to binary you will get the following:

0000 0000 0000 0111 0000 0000 0000 0000

which means that you give CHANGE_STATE, CHANGE_PERMIT, and CHANGE_OWNER (since bits 17,18, and 19 are 1 )extended permission to a user or group and

since bits 1 and 2 are 0 they are also on, so you also gave execute_proc and change_location.
