Deletes an access control entry (ACE) from a directory's access
 control set (ACS). The optional argument [as default] indicates the
 ACE to be deleted is a default ACE. If this argument is not used,
 DECdns assumes the ACE is associated with the directory and not its
 contents.

 SYNOPSIS

      REMOVE DIRECTORY directory-name ACCESS principal

      [AS DEFAULT]

 Arguments

 directory-name

 The full name of the directory.

 principal

 The principal for whom access is being removed. You can specify
 a principal as a group name, a collection of principals denoted
 with wildcards (for example, .org.name*), or an individual name
 in the format, nodename.username. To specify a DNS Version 1-style
 principal, use the format nodename::username.

 ACCESS RIGHTS
 You must have control access to the directory whose ACS is being
 modified.
