mnthome(1)                BSD General Commands Manual               mnthome(1)

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 auto-mount automount
     mount 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 cate-gory category
     gory (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/Net-work/Servers/. /var/automount/Network/Servers/.
             work/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 auto-matically automatically
     matically get put back into that same directory when mnthome leaves.  If mnthome works, then your cur-rent current
     rent 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 mount-ing mounting
     ing 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.
