I&#39;ve been trying to research how to correctly escape search filters, and I can&#39;t find any single<br>reliable source that makes sense.<br><br>I look at RFC 2253 (<a href="http://www.ietf.org/rfc/rfc2253.txt">http://www.ietf.org/rfc/rfc2253.txt</a>) section 2.4,<br>
and this IBM webpage (<a href="http://publib.boulder.ibm.com/infocenter/iseries/v5r3/index.jsp?topic=/rzahy/rzahyunderdn.htm">http://publib.boulder.ibm.com/infocenter/iseries/v5r3/index.jsp?topic=/rzahy/rzahyunderdn.htm</a>),<br>
and they both seem to suggest that you need to escape (for example) the &#39;+&#39; sign.<br><br>But when I escape a search filter like this:<br>(&amp;(objectclass=person)(facsimileTelephoneNumber=+1234))<br>to this:<br>(&amp;(objectclass=person)(facsimileTelephoneNumber=\+1234))<br>
it results in a bad filter.<br><br>My hunch is that perhaps DNs, attribute names, and attribute values are all escaped different.<br><br>Is there a simple explanation online on how to escape search filters?<br><br>Thanks,<br>
