/home directory is protected in mac osx and you need to remove the auto mount by editing the file
/etc/auto_master and replace the following line
/home auto_home -nobrowse,hidefromfinder
#/home auto_home -nobrowse,hidefromfinder
But after that you must restart the system like an old fashion windows :( to apply those changes. Is there any way to avoid restarting of system because it's really cumbersome and frustrating specially when you are in between of something very important.
