title: Can't query for description from SQL using ADSI
body: <p>I have a linked server using ADSI. I can successfully query for most attributes except <code>description</code>. </p>
  
  <p>My query:</p>
  
  <pre><code>SELECT * FROM OpenQuery (ADSI,  
      'SELECT description,sn,givenName
      FROM  ''LDAP://mydomain.com/OU=users,DC=com,DC=mydomain'' 
      WHERE title&lt;&gt;''Virtual'' AND (userAccountControl=''66048'' OR 
      userAccountControl=''512'')') 
  ORDER BY sn
  </code></pre>
  
  <p>It throws this error:</p>
  
  <pre><code>"Cannot get the data of the row from the OLE DB provider "ADSDSOObject" for linked server "ADSI". Could not convert the data value due to reasons other than sign mismatch or overflow."
  </code></pre>
  
  <p>What is the problem here?</p>
