The two script are often combined together to add a new user and assign it to a group.  Here we present several scenario that the command can be used:

To add a linux user named user1 to the directory:

smbldap-groupadd user1
smbldap-useradd -g "user1" -m user1
smbldap-passwd user1

To add a windows user named user2, who belongs to the default group (513, system user) and doesn't have a login shell and a home directory /dev/null  to the directory:

smbldap-useradd -a -m -s /bin/false -d /dev/null -F "" -P user2

To add a user named user 3 who is both a windows and linux user:

smbldap-groupadd user3
smbldap-useradd -a -g "user3" -m -P user3

To add a system user named nagios, which belongs to the group nagios and does not have a login shell and home directory:

smbldap-groupadd nagios
smbldap-useradd -s /bin/false -g "nagios" nagios

A windows machine can be added into the directory for it to join the domain:

smbldap-useradd -w computer1

 

Password can be changed using the normal linux passwd command.
