# Dump NIS+ entries to Tru64 5.0 C2 databases.
#
# Server: Solaris 8 NIS+ with ssh installed
# Client: Tru64 5.0 with sshd installed

# This script will:
#
# Dump group.org_dir with gid >= 1000 && gid < 60000 to /etc/group
# Dump auto_home.org_dir to /etc/auto_home
# Dump passwd.org_dir with uid >= 1000 && uid < 60000 to /etc/passwd
# Dump passwd.org_dir with uid >= 1000 && uid < 60000 to |edauth

# it will keep "system" and not modified entries
# it won't honour lastchg/min/max/warn/inactive/expire solaris flags
