LDAP manager attribute

Question

I am creating an LDAP class that contains a function that returns the username of the manager of the current user.

I know that I can use the "manager" attribute to return CN = "name", OU = "group", DC = "company", etc.

I specifically want the managers username, does anyone know if there is an attribute string that I can send to LDAP that specifically gets the managers-only username? If not, is there an alternative method?

Answer 1

Now I decided to solve this problem.

Basically, an attribute managerin LDAP returns the distinguishedNamemaanger user attribute.

// return manager for a given user
public UserPrincipal GetManager(PrincipalContext ctx, UserPrincipal user) {
    if (user != null) {
        // get the DirectoryEntry behind the UserPrincipal object
        var dirEntryForUser = user.GetUnderlyingObject() as DirectoryEntry;

        if (dirEntryForUser != null) {
            // check to see if we have a manager name - if so, grab it
            if (dirEntryForUser.Properties["manager"] != null && dirEntryForUser.Properties["manager"].Count > 0) {
                string managerDN = dirEntryForUser.Properties["manager"][0].ToString();
                // find the manager UserPrincipal via the managerDN 
                return UserPrincipal.FindByIdentity(ctx, managerDN);
            }
        }
    }
    return null;

- : , .NET 3.5, System.DirectoryServices, System.DirectoryServices.AccountManagement:

// return manager for a given user
public UserPrincipal GetManager(PrincipalContext ctx, UserPrincipal user)
{
    UserPrincipal result = null;

    if (user != null)
    {
        // get the DirectoryEntry behind the UserPrincipal object
        DirectoryEntry dirEntryForUser = user.GetUnderlyingObject() as DirectoryEntry;

        if (dirEntryForUser != null)

             {
                 string managerDN = dirEntryForUser.Properties["manager"][0].ToString();

                 // find the manager UserPrincipal via the managerDN 
                 result = UserPrincipal.FindByIdentity(ctx, managerDN);
             }
        }
    }

    return result;
}

, . :

// Create default domain context
PrincipalContext ctx = new PrincipalContext(ContextType.Domain);

// find yourself - you could also search for other users here
UserPrincipal myself = UserPrincipal.Current;

// get the manager for myself
UserPrincipal myManager = GetManager(ctx, myself);
