Change authentication from local NetInfo to Active Directory

Can it be done if I already have a home directory?

eg. Local NetInfo has username1 and password1 with home directory1.

I would like to authenticate against AD but keep my home directory1. I currently have an AD account with username1 and password2.

From what I can see, Mac OSX will check local NetInfo first and then go look through active directory. Since I have a local account with username1 that one gets picked first and it won’t get to AD.

I would like it to check username1 from AD and use my local home directory. If anyone knows of a easy way to do this, it would be much appreciated.

Thanks.
