provide the server with the following parameters.
 Server Name — the prefix osx must appear in front of the OSx station
name.

 Match String (optional) — enter a text search string. You can use the
standard wildcard * (match any) and ? (match single) characters.
 Start Index (optional) — enter an integer. The server uses the index as
a placeholder when there is more data to return than there are output

the beginning of its database.

bit_defs relation for that
attribute.

 Error Information (optional, but recommended) — designate a location
to display error messages. This location must be the same size as the
