Add new user (LDAP)
To get a untaken UID for the new accont, use nextUID.py placed in '/opt/scripts'. Note that the UID may be already in use on grape.
To add a group of new users with similar uid, use script ldapBatchAddUser.py placed in '/opt/scripts/'. You will have to run it as root, and keep in mind the following things.
This program helps to create multiple user accounts on the fly.
In order to use it, you have to provide some basic information
of the new accounts. The new accounts will be named as "BASE$N",
in which "BASE" is the base name, and $N is the count. You have
to specify the starting number of $N. Users' home directory
will be /home/BASE/BASE$N, and bear in mind that this program
does not create /home/BASE automatically. The program will invoke
"nextUID.py" to set UIDs for the new accounts, However, you still
have to take care of the GID issue yourself. All new accounts
will use "BASE" as their passwords.
Modify the program yourself to make it better suit your need.
Use CTRL+C to interrupt the program when typing something wrong.
