Connecting to a remote active directory and create/update users

Hi,

We are writing a http service which will read, insert, update and (possibly) delete users, including reset their passwords. It will also create, update, delete and read password settings objects (or some equivalent), and assign those to users. The data store for this is AD. We need an OU to develop against. .

web server (Domain A)

Active Directory (Domain B)

there is no trust relationship between the two domains. but I(in Domain A) have user account DomainB\userbb.

can you please advice on how to go on creating/updating users in Domain B active directory. what permissions/info do i need. a example code sample would be great.

Thanks
