Custom schema template/class in Active Directory using C#

Question

Hi

I need to distribute a string-value (a wcf-service-address) to a network of clients in the same domain. I figured AD would be a good place to store this kind of information, or is it overkill for only one string-value?

To do this it seems I have to add a custom AD-class/schema template. But how? I can't find any good information about how to do this in C#...
