Proper Use of adduser.conf

[Martin McCormick <martin@dc.cis.okstate.edu>]

	We have set up a backup server and the samba share
accounts we have on the system need to be in a file system that
is very large so I modified /etc/adduser.conf to put them in as
follows:

# The DHOME variable specifies the directory containing users' home
# directories.
DHOME=/srv/backups

# FIRST_[GU]ID to LAST_[GU]ID inclusive is the range of UIDs of dynamically
# allocated user accounts/groups.
FIRST_UID=28000
LAST_UID=29999

FIRST_GID=28000
LAST_GID=29999

	When I ran adduser, it appeared to work and placed the
home directory in /srv/backups but if you su - testuser, it
complains that there is no home directory.

	The rest of the adduser.conf file is left as is.

	Is there a way to make these accounts work normally even
though they are in a different file system?

Thank you.
