a 2nd call to getAttribute will produce the same text returned in the first 
call, if the first call attribute 'cn' contains data and the second call 
attribute 'secretary' is a missing attributr from the result.
<BR>
  <jndi:getAttribute ref='result' attribute='cn' id='cnval' 
multivalue='iterate'>
      <%=cnval%><BR>
  </jndi:getAttribute>
<BR>
  <jndi:getAttribute ref='result' attribute='secretary' id='asecval' 
multivalue='iterate'>
      <A HREF=MVC?PAGE=DISPLAY&dn=<%=asecval%>>Admin Link</A><BR>
  </jndi:getAttribute>
