ASP.NET Active Directory Membership Provider - Storing Extra Profile Fields in AD

Question

I have set up an Active Directory Membership provider and can successfully create and log in users into the active directory with an ASP.NET application.

However, the active directory has other fields besides Username/Password such as First Name, Last Name , Telephone Number etc. Is there any way for me to be able to gather this information using my ASP.NET website and store it in the Active Directory?

I understand that I need to use a Profile Provider and I can technically set it up to use an SQL DB to store the extra profile information, but is there any way I can store the information directly in the fields available in the Active Directory? As far as I know there is no ActiveDirectoryProfileProvider.

Thank you,
