This attribute lists the NSAP addresses that directory
 applications can use to communicate with this DSA and modify
 directory information. Any application attempting to use
 an unlisted NSAP is not allowed to modify information held by
 this DSA. It might be able to read information, subject to
 the Reader_NSAPs attribute. Having write access automatically
 gives read access as well.

 Note that this attribute is not the recommended way to implement
 access control. Refer to HP Enterprise Directory
 - Management for access control advice.

 Syntax:
 	SET DSA WRITER NSAPS {<address>, ....}

 where <address> is the NSAP address, for example:

 	SET DSA WRITER NSAPS {%x49002aaa00040008aa21}

 You can specify the leading characters of an NSAP to indicate
 that access is allowed for any application using an NSAP beginning
 with that sequence of characters. For example:

 	SET DSA WRITER NSAPS {%x49002a}

 The default value is an empty set of NSAP addresses, indicating
 that an application can use any NSAP.

 Note also that the DSA refers to the value of this attribute
 whenever it receives a new connection. Once a connection is
 established, the caller is allowed write access for as
 long as the connection lasts. Changing the value of the
 attribute has no effect on existing connections, only on
 subsequent connections.
