Question on OpenRowSet and PageSize

[FancyPrairie]

I've added Active Directory as a linked server so I can query Active Directory using OpenQuery. The query looks something like this:

SELECT *
FROM OPENQUERY(ADSI,
    'SELECT sn
     FROM ''LDAP://OU=whatever,DC=whatever'' 
     WHERE objectCategory = ''Person'' AND 
           objectClass= ''user'' ')

The problem with this query is that it only displays 1000 records. I know I can change the MaxPageSize on the server, but, for various reason, cannot do that.

Supposedly I should be able to change the Page Size using OpenRowSet rather than OpenQuery. But I still can't seem to get the query to display more than 1000 records.

Here's my query. What am I doing wrong?

SELECT *
FROM OPENROWSET('AdsDsoObject', 'User ID=Me;Password=MyPassword;ADSI Flag=0x11;Page Size=10000', 
     'SELECT sn
      FROM ''LDAP://OU=whatever,DC=whatever''
    WHERE
        objectCategory = ''Person''
        AND objectClass = ''user'' ')
