Removing a home directory

[Art Alexion]

something broke my active directory authentication.  I can log in as one of 
the other domain users (without sudo access) but not as myself because 
permissions have been corrupted.

I am willing to delete my home directory.  Can I do this and have it 
automatically regenerated?  Do I have to remove myself as a user and then add 
myself again?

Fortunately I added a root account before this happened; otherwise no one with 
sudo privileges could log in to do this stuff.
