You can use the command-line interface (CLI) or the management GUI to change users on the
system.
System users must provide either a password, a Secure Shell (SSH) key, or both.
Local users are authenticated through the authentication methods that are on the system.
You can create two categories of users that access the clustered system (system). These user types are based on how they authenticate to the system:
- Some users must provide an SSH password (or if not possible an SSH key).
- If a user needs access to the management GUI, a password is needed for the user.
- If the user requires access to the command-line interface (CLI), a valid password and SSH key can be used.
- Users must be part of a user group that is defined on the system.
Remote users should also configure local credentials if they need to access the
system when the remote service is down. Remote users have their groups that are defined by the
remote authentication service.
To change a user in the management GUI, select . Right-click the user and select Modify from the
Actions menu.
To change a user in the CLI, follow these steps:
- Issue the chuser CLI command to change
the attributes of an existing user.
For example:
chuser -usergrp group_id_or_nameuser_id_or_name
where
the
group_id_or_name specifies the new group for
the user and
user_id_or_name specifies the user
to be changed.
- Issue the chcurrentuser CLI command
to change the attributes of the current user.
For example:
chcurrentuser -nokey
where
the
nokey parameter specifies that the SSH key
of the user is to be deleted.
- Issue the lscurrentuser CLI command
to display the name and role of the logged-in user.
For
example:
lscurrentuser
The name and the role
of the user are displayed.
