* $name: ModifyACL.java
* $description: modifyACL.java first modifies entryDN's ACL values to grant
* trusteeDN the read, write, and delete entry rights. It then
* displays entryDN's ACL values. Finally it removes entryDN's
* modified ACL value.
*
* ACL (Access Control List) is a multivalued optional attribute.
* An entry's ACL values define which other entries (trustees)
* have what kinds of access to the entry itself and its
* attributes.
*
* Each of the ACL value is in the format of
* "privileges#scope#subjectname#protectedattrname".
* privileges: ORed bits to indicate the rights.
* scope: either 'entry' or 'subtree'.
* subjectname: trustee DN.
* protectedattrname: [Entry Rights], or [All Attributes Rights],
* or a single attribute name.
