NAME

     mnthome -- mount an AFP (AppleShare) home directory with the correct privileges

SYNOPSIS

     mnthome [-v] [-d] [-m mntpath] [-n] [-b] [-p password] [-i] [-x mount point] [-u] [-s]

DESCRIPTION

     The mnthome command unmounts the AFP (AppleShare) home directory that was automounted as guest, and remounts it with the correct privileges
     by logging into the AFP server using the current username and password.  This command also allows you to have guest access turned off on your
     AFP server too and still have AFP home directories work with "su".

     When you ssh into another computer using an account that has an AFP home directory or you "su <netuser>" where <netuser> is an AFP home
     directory user, then the resulting home directory will not have the correct access privileges.

     This is because automount is assuming NFS behavior which assumes that all computers share the same user/group privileges and mounts volumes
     using "no security" and lets the client enforce privileges based on the current user.

     AFP is different since the privileges are based on the user that logged into the server.  Since automount does not put up an authentication
     dialog asking for an user name and password, automount mounts the fileserver using guest login.  Thus you end up with getting the world
     access privileges and the privileges are shown via "mapping".  You also would have to allow guest access to the server to that sharepoint.

     Mapping makes all the files/folders appear like they are owned by the current user.  Even those items not really owned by the current user
     show up as being owned by the current user.  The server provides user access rights (UARights) which is a summary of what the access rights
     are regardless of the category (owner, group, world) from which they were obtained.  When doing "mapping", the AppleShare client will take
     these UARights and show them as the owner rights.	So, everything looks like it is owned by the current user and the owner rights are set to
     the UARights.  Thus if you had access to that file/folder before, then you still do.

     The options are:

     -v      Display version number.

     -d      Print debugging information.

     -m      Alternative mount point is specified with the -m option followed by a path to an existing directory.  Normally, the volume is mounted
	     in /Network/Servers/ or /var/automount/Network/Servers/.

     -n      Do not force the unmount of the previous mount point.

     -b      Exec the user's shell after mount of home.

     -p      A password may be specified with the -p option followed by a password.  If this option is not used, then the user will be prompted to
	     enter in a password.

     -i      Display information about the AFP home mount point.

     -u      Attempt to unmount the current home directory mount.

     -x      This option must be followed by a path to an existing AFP mount point.  Display information about the mount point.

     -s      Skip preflight check to see if the currently mounted home directory is already correctly mounted for the user.

EXAMPLES

     The following example illustrates how to mount an AFP home directory:

	   mnthome

     This example shows how to print the debugging information and provide a password:

	   mnthome -d -p foobar

BUGS

     I get the mounting url from the "home_loc" attribute and the mountpath from the "home" attribute (with the path from home_loc subtracted
     out).  If your AFP home directory automounts in a different location, then you need to use the -m option to specify an alternative mount
     point.

     I cant figure out how to cd out of the current home dir so I can do the unmount and then restore the user back into the new home dir.  If you
     are in the AFP home directory when you use mnthome, you automatically get put back into that same directory when mnthome leaves.  If mnthome
     works, then your current directory is a dead directory and you need to "cd ~" to get to your new home directory.

     If the server with the home directory was already mounted by another user, you will not be able to replace it with a mount made by your user
     id.  The original mount must be first unmounted by the mounting user or root.

HISTORY

     The mnthome command first appeared Mac OS X version 10.3.

RETURN VALUES

     0			mnthome successfully remounted the AFP home directory.

     [EINVAL]		Invalid arguements were passed in.

     [EPERM]		The current AFP home directory could not be unmounted by mnthome because the current user does not have the correct
			access.  The current AFP home directory was probably mounted by another user first.

     [EAUTH]		Incorrect password.
