Regading NAS PowerVault NF 500 configuration guide

Hi !!!!!!

we have purchased the Dell PowerVault NF 500 NAS Storage Box with Window Storage server 2003 is Installed .we have LDAP server for authentication the user in network for accessing network resources.all ubuntu users on client side use ubuntu(LDAP server ) for user authentication.when a user logon on client side machine his home directory is created on client machine .

but we want to use the NAS storage device to store the home directories of user.we want to implement that ,whenever a user logon his home directory is created on  powerValut NF 500 storage device so that all user data is stored centrally for taking the backup .

kindly anybody know this solution .please help me to solve this so that i can solve this assignment ,given by my manager.
