You can use the UserPrincipal class together with a class named DirectoryEntry to access some properties of the master. This class represents a node or object in the Active Directory hierarchy. The class UserPrincipal inherits from a class Principal which in turn is associated with a DirectoryEntry .
To get the DirectoryEntry over of a Principal we use the GetUnderlyingObject method of this class. It turns out that every DirectoryEntry object has a collection called Properties that has the ADDS properties for that active directory object. This property is of type PropertyCollection and has a Contains method to check if a property is specified for that AD entry.
Basically this is done like this:
directoryEntry.Properties.Contains("propriedade");
This is a bool that says whether the property is there or not. If the property is you can access its value with array syntax and accessing the Value property:
directoryEntry.Properties["propriedade"].Value.ToString();
With this idea, the best you can do is create extension methods to make everything more flexible. Create an extension method for the Principal class that returns a property of the over DirectoryEntry like this:
public static string GetProperty(this Principal principal, string propriedade)
{
DirectoryEntry directoryEntrySobrejacente = principal.GetUnderlyingObject() as DirectoryEntry;
if (directoryEntrySobrejacente.Properties.Contains(propriedade))
{
return directoryEntrySobrejacente.Properties[propriedade].Value.ToString();
}
else
{
return string.Empty;
}
}
Then create extension methods for the specific properties you want. For example, a GetDepartment method to return the department property by passing the property name to string.
I do not know much about AD so I do not know if this approach works exactly for your problem. Try it there and say it worked out.
