What does the numeric value of ACL mean in an LDAP export?

When exporting objects, you may see ACL attributes exported as well.  For example:

# extended LDIF
#
# LDAPv3
# base <o=MyOrg> with scope baseObject
# filter: (objectclass=*)
# requesting: ALL
#

# MyOrg
dn: o=MyOrg
ACL: 1073741856#subtree#cn=MyOrg,cn=User Management,cn=Role Based Service,ou=EN
 T,o=MyOrg#sasAuditConfiguration
ACL: 1073741863#subtree#cn=MyOrg,cn=User Management,cn=Role Based Service,ou=EN
 T,o=MyOrg#cn
ACL: 1073741855#subtree#cn=MyOrg,cn=User Management,cn=Role Based Service,ou=EN
 T,o=MyOrg#[Entry Rights]
ACL: 3#subtree#cn=UNIX Workstation - server101,ou=SERVERS,ou=CITY,ou=ST,o=MyOrg
 #passwordExpirationTime

The number before the first # in each ACL line is the permission or rights assigned.  This TID will address translating those values to human readable form.

The number before the first # is in decimal.  Convert the decimal value to hexadecimal (base 16) and select the privileges from the following table (starting with the largest value, or at the bottom):

ENTRY PRIVILEGES
Decimal	Hexadecimal	Description
1	1	entry_browse
2	2	entry_add
4	4	entry_delete
8	8	entry_rename
16	10	entry_supervisor
64	40	entry_inherit_ctl
ATTRIBUTE PRIVILEGES
1	1	attr_compare
2	2	attr_read
4	4	attr_write
8	8	attr_self
32	20	attr_supervisor
64	40	attr_inherit_ctl
Privilege for both Entries and Attrs
536870912	20000000	Dynamic Groups
1073741824	40000000	iManager Role Based Svcs

So in the case of:

ACL: 1073741863#subtree#cn=MyOrg,cn=User Management,cn=Role Based Service,ou=EN
 T,o=MyOrg#cn

The ACL value is 1073741863 (decimal).
This converts to 40000027 hex (or 0x40000027).
Starting at the bottom of the above table, this translates to:

0x40000000  = iManager Role Base Services granted privilege.
0x00000020  = Supervisor Permission to the attribute indicated (attr_supervisor)
0x00000004  = Write Permission to the attribute indicated (attr_write)
0x00000002  = Read Permission to the attribute indicated (attr_read)
0x00000001  = Compare Permission to the attribute indicated (attr_compare)
