Can anyone please clarify where exactly this path is supposed to be?

<authentication defaultProvider="ADSIAuthenticationProvider">
      <providers>
        <clear />
        <add name="ADSIAuthenticationProvider" type="DotNetNuke.Security.Authentication.ADSIProvider, DotNetNuke.Authentication.ADSIProvider" providerPath="~\Providers\AuthenticationProviders\ADSIProvider\" />
      </providers>
    </authentication>

What is the providerPath telling the application here in the web.config? Obviously, it's pointing it somehow ...but, looking through the structure I don't see this physical path anywhere. I'm sorry in advance if this is the lamest question ever, but I can't stand not knowing! :-) Any pointers are VERY much appreciated!

Hi Mike, man you're quick! I think (hope) I've tracked my issue down to a missing letter in a database field. Hey let me ask you this - I'm trying to extend the AD provider and i've created a procedure to grab all the Active AD groups in our system. Now, I would like to cache that object, but I haven't worked with the DNN caching before. Here is what I have...Does this look right? Also, now, if I want to call the object from somewhere else in the application ...what is the best way to do it? Oh...and also on the AddFilter how would I use two filters? for example, if I wanted to achieve: "(&(objectClass=group)(cn=CS_*))". is it as simple as adding another filter? Thanks very much!!

 Public Overrides Function GetAllGroups() As System.Collections.ArrayList

            Dim _config As DotNetNuke.Authentication.ActiveDirectory.Configuration = ActiveDirectory.Configuration.GetConfig()
            Dim strCacheKey As String = GroupCacheKey

            Dim dirEntries As ArrayList = CType(DataCache.GetCache(strCacheKey), ArrayList)

            If dirEntries Is Nothing Then
                Dim RootDomain As Domain = GetRootDomain()

                'create instance fo the direcory searcher
                Dim objSearch As New Search(RootDomain)

                'set the search filter
                objSearch.AddFilter(Configuration.ADSI_CLASS, ADSI.CompareOperator.Is, ObjectClass.group.ToString())

                'populate array list with group objects
                dirEntries = objSearch.GetEntries
                DataCache.SetCache(strCacheKey, dirEntries, 600)
            End If

            Return dirEntries
        End Function

*had to edit...the code got all chewed up.

Hi Mike - thanks very much for the great resource pointers. I'm pretty sure I've got the cache thing working fine, but I'm a little confused still on the filters. I took the same procedure and modified it to return a datatable. Initially, the way I posted it..I bound it to a datagrid and I got back 118 results of "directoryservices.entry...". Needless to say I returned the items, but no properties I suppose. Anyhow, so I am now returning a datatable, but everytime I get to "if searchresults.count > 0", then it just hangs. Viewing the locals window, it looks like there is somekind of error retrieving any info from AD. The weird part is that it only seems to happen if i add the second filter... from looking below, can you tell if there is anything i'm doing wrong?
