Unable to find User after specifying a container for PrincipalContext

Question

I'm attempting to find a User by username in Active Directory.

This works:

const string Domain = "SLO1.Foo.Bar.biz";
const string Username = "sanderso";

PrincipalContext principalContext = new PrincipalContext(ContextType.Domain, Domain);
UserPrincipal userPrincipal = UserPrincipal.FindByIdentity(principalContext,  Username);

This does not:

const string Domain = "SLO1.Foo.Bar.biz";
const string Container = "CN=Users,DC=SLO1,DC=Foo,DC=Bar,DC=biz";
const string Username = "sanderso";

PrincipalContext principalContext = new PrincipalContext(ContextType.Domain, Domain, Container);
UserPrincipal userPrincipal = UserPrincipal.FindByIdentity(principalContext, Username);

I receive the error message:

There is no such object on the server.

here's a screenshot of my ActiveDirectory setup:

I've also tried using the following Container:

const string Container = "OU=Users,DC=SLO1,DC=Foo,DC=Bar,DC=biz";

this was equally unsuccessful.

How can I specify my container while accessing the 'Users' container? I'm trying to do this as an initial, simple setup before introducing a lookup with more complicated requirements. So, I'd rather not settle for the simple solution because I am going to have to troubleshoot this anyway, I believe.

Solution

I figured it out :)

First, I used the following software to ensure that I was generating the proper container string:

This confirmed that my string was pretty much correct, aside from missing a port, but it just needed some fussing.

The correct usage is:

const string Domain = "SLO1.Foo.Bar.biz:389";
const string Container = @"DC=Foo,DC=Bar,DC=biz";
const string Username = @"sanderso";
PrincipalContext principalContext = new PrincipalContext(ContextType.Domain, Domain, Container);
UserPrincipal userPrincipal = UserPrincipal.FindByIdentity(principalContext,  username);

I hope that I was able to help you to figure out in getting your Answer Sean.. you can also Accept your answer glad I could help O totally forgot about :389 I must have been really tired last night how could I have over looked that..LOL

But Users is a default container, your answer doesn't specify how to name the container. something like const string Container = @"CN=Interns,DC=Foo,DC=Bar,DC=biz";
