The DNN Label user control has a "ControlName" attribute, that I assume is supposed to render an HTML "For" attribute for an associated input control.  

I have it set, but it is not rendering the For attribute.  Any ideas?

ASPX Markup:

<dnn:Label id="allowAnonymousLabel" runat="server" controlname="allowAnonymousCheckbox" suffix=":" />

<asp:CheckBox ID="allowAnonymousCheckbox" runat="server" />

HTML Rendered:

<div>

<div style="position: relative;">

<label>

<span id="dnn_ctr428_ModuleSettings_Settings_allowAnonymousLabel_lblLabel">Allow Anonymous Posts:</span>

</label>

<a id="dnn_ctr428_ModuleSettings_Settings_allowAnonymousLabel_cmdHelp" tabindex="-1" href="javascript:__doPostBack('dnn$ctr428$ModuleSettings$Settings$allowAnonymousLabel$cmdHelp','')"></a>

<div id="dnn_ctr428_ModuleSettings_Settings_allowAnonymousLabel_pnlHelp" style="position: absolute; right: -29%; top: -84px;">

<div style="visibility: hidden;">

<span id="dnn_ctr428_ModuleSettings_Settings_allowAnonymousLabel_lblHelp">If selected ANY user can post an entry to the guestbook, if not selected only authenticated users can post</span>

<a href="#"></a>
