OK - this works:<br />

deSearch.Filter = &quot;(&amp;(objectClass=user)(obje<wbr />ctCategory<wbr />=person)(d<wbr />epartment=<wbr />APDSLN))&quot;;<wbr /><br />
<br />
But for soem reason, this does not - when I include the extra department criteria, nothing is returned - when I do one or the other, it works individually, etc. (above):<br />

<div>
You use only one '&amp;' operator, and this condition<br />
&nbsp; &nbsp;objectClass=user AND objectCategory=person AND department=APDSLN AND department=APDSLI<br />
&nbsp;cannot be true. <br />
<br />
&nbsp;You need to use '|' (meaning OR) operator also, this way:<br />
deSearch.Filter = &quot;(&amp;(objectClass=user)(obje<wbr />ctCategory<wbr />=person)(|<wbr />(departmen<wbr />t=APDSLN)(<wbr />department<wbr />=APDSLI)))<wbr />&quot;; <br />
&nbsp; &nbsp;which you can translate:<br />
&nbsp; &nbsp; (objectClass=user) AND (objectCategory=person) AND (department=APDSLN OR department=APDSLI).<br />
<br />

AD Query - Multiple Criteria

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
