Check if a user is in a OU

To get all users from an AD group is very simple:

groupName = "an_ad_group";
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);
GroupPrincipal grp = GroupPrincipal.FindByIdentity(ctx, IdentityType.Name, groupName);
var principals = grp.GetMembers(true);

But what about an OU? There is no OrganizationUnitPrincipal… Well, there is a solution: to instantiate a context for your OU:

So if you want to check if a user in a OU:

internal static bool IsUserInOu(string ou, string name)
	var domain = "takana.local";
	var container = string.Format("OU={0}, DC=takana, DC=local", ou);
	var ctx = new PrincipalContext(ContextType.Domain, domain, container);
	var up = new UserPrincipal(ctx);
	var ps = new PrincipalSearcher(up);

	var results = ps.FindAll();
	return results.Any(p => p.Name.Equals(name, StringComparison.InvariantCultureIgnoreCase));

To avoid hardcoding domain and root container, we can retrieve the current domain.
