Unable to connect to ADAM with Windows domain\username

I'm having some difficulty connecting to an ADAM instance from my Commerce Server 2007 ASP .NET solution, and I believe it relates to my config file somehow. The short version is that I can connect to ADAM through ADAM-ADSIEdit with my current username/password, but when I put this in my web.config i get "Parser Error Message: Logon failure: unknown user name or bad password."

<connectionStrings>
<add name="LDAPConnection" connectionString="LDAP://<domain/>:389/<Partition DN>" />
</connectionStrings>

<membership defaultProvider="MembershipADAMProvider">
  <providers>
    <add name="MembershipADAMProvider"
        type="System.Web.Security.ActiveDirectoryMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
        connectionStringName="LDAPConnection"
        connectionProtection="None" 
        connectionUsername="<domain>\<username>"
        connectionPassword="<password>"/>
  </providers>
</membership>   

I've tried a bunch of things to fix this and haven't come up with any kind of reasonable solution. I started with just the connection String and no username or password. I got an error saying that I could not make a secure connection. that's when I added the connectionProtection="None" line. Then it said I could not use default credentials without a secure connection, so I added the Username and Password fields. When I created the ADAM instance, I used the current Windows login credentials. I've tried to use my windows login credentials here in web.config, and I've tried with various domain开发者_高级运维 names, pretty much anything I could think of. I'm totally lost why I cant bind with ldp and I can connect in ASIEdit with these domain\username and password but can't from my CommerceServer ASP .NET application...Is there some other step I'm missing?

Thanks, John

You should follow the information here, there is a lot of good stuff about secure connections and how to disable them within your ADAM instance for development purposes.
