Apache 2.0, WebDav and User Permissions

I am new to Apache and Webdav so bare with me.

I am trying to setup WebDav to restrict users to specific directories,
can this be done? If so, can anyone provide an example of how I would
do this in the server config file or via .htaccess?

Example:

Company Shared Directory (All valid users have access)
user1 directory (only user "user1" has access)
user2 directory (only user "user2" has access)
user3 directory " "
