Hi all, RH8.0 When I tried to add user "as root" # smbpasswd -a AAA New SMB password: Retype new SMB password: unable to open passdb database. Added user AAA AAA is an existing user of RH8.0 with password to login. What is the problem of "unable to open passdb database" # which passdb /usr/bin/which: no passdb in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/root/bin) # locate passdb [root@localhost root]# How to correct it. Thanks in advance. Stephen Liu
