Manage users using the CLI
This page describes the management of users licensed to work with the WEKA system.
Using the CLI, you can:
Create a local user
Command: weka user add
Use the following command line to create a local user:
weka user add <username> <role> [password] [--posix-uid uid] [--posix-gid gid]
Parameters
Example:
$ weka user add my_new_user regular S3cret
This command line creates a user with a username of my_new_user
, a password of S3cret
and a role of a Regular user. It is then possible to display a list of users and verify that the user was created:
Using the weka user whoami
command, it is possible to receive information about the current user running the command.
To use the new user credentials, use theWEKA_USERNAME
and WEKA_PASSWORD
environment variables:
Change a local user password
Command: weka user passwd
Use the following command line to change a local user password:
weka user passwd <password> [--username username]
Parameters
Note: If necessary, provide or setWEKA_USERNAME
or WEKA_PASSWORD.
Revoke user access
Command: weka user revoke-tokens
Use the following command to revoke internal user access to the system and mounting filesystems:
weka user revoke-tokens <username>
You can revoke the access for LDAP users by changing the user-revocation-attribute
defined in the LDAP server configuration.
Parameters
Note: NFS and SMB are different protocols from WekaFS, which require additional security considerations when used. For example, The system grants NFS permissions per server. Therefore, manage the permissions for accessing these servers for NFS export carefully.
Update a local user
Command: weka user update
Use the following command line to update a local user:
weka user update <username> [--role role] [--posix-uid uid] [--posix-gid gid]
Parameters
Delete a local user
Command: weka user delete
To delete a user, use the following command line:
weka user delete <username>
Parameters
Example:
$ weka user add my_new_user
Then run theweka user
command to verify that the user was deleted:
User sign in
When a login is attempted, the user is first searched in the list of internal users, i.e., users created using theweka user add
command.
However, if a user does not exist in the Weka system but does exist in an LDAP directory, it is possible to configure the LDAP user directory to the Weka system. This will enable a search for the user in the directory, followed by password verification.
On each successful login, a UserLoggedIn
event is issued, containing the username, role and whether the user is an internal or LDAP user.
When a login fails, an "Invalid username or password" message is displayed and a UserLoginFailed
event is issued, containing the username and the reason for the login failure.
When users open the GUI, they are prompted to provide their username and password. To pass username and password to the CLI, use the WEKA_USERNAME
and WEKA_PASSWORD
environment variables.
Alternatively, it is possible to log into the CLI as a specific user using theweka user login <username> <password>
command. This will run each CLI command from that user. When a user logs in, a token file is created to be used for authentication (default to ~/.weka/auth-token.json
, which can be changed using the --path
attribute). To see the logged-in CLI user, run theweka user whoami
command.
Note: Theweka user login
command is persistent, but only applies to the server on which it was set.
Note: If theWEKA_USERNAME
/WEKA_PASSWORD
environment variables are not specified, the CLI uses the default token file. If no CLI user is explicitly logged-in, and no token file is present the CLI uses the default admin
/admin
.
To use a non-default path for the token file, use the WEKA_TOKEN
environment variable.
Authenticate users from an LDAP user directory
To authenticate users from an LDAP user directory, the LDAP directory must first be configured to the Weka system. This is performed as follows.
Configure an LDAP user directory
Command:
weka user ldap setup
weka user ldap setup-ad
One of two CLI commands is used to configure an LDAP user directory for user authentication. The first is for configuring a general LDAP server and the second is for configuring an Active Directory server.
To configure an LDAP server, use the following command line:
weka user ldap setup <server-uri> <base-dn> <user-object-class> <user-id-attribute> <group-object-class> <group-membership-attribute> <group-id-attribute> <reader-username> <reader-password> <cluster-admin-group> <org-admin-group> <regular-group> <readonly-group> [--start-tls start-tls] [--ignore-start-tls-failure ignore-start-tls-failure] [--server-timeout-secs server-timeout-secs] [--protocol-version protocol-version] [--user-revocation-attribute user-revocation-attribute]
To configure an Active Directory server, use the following command line:
weka user ldap setup-ad <server-uri> <domain> <reader-username> <reader-password> <cluster-admin-group> <org-admin-group> <regular-group> <readonly-group> [--start-tls start-tls] [--ignore-start-tls-failure ignore-start-tls-failure] [--server-timeout-secs server-timeout-secs] [--user-revocation-attribute user-revocation-attribute]
Parameters
View a configured LDAP User Directory
Command:
weka user ldap
This command is used for viewing the current LDAP configuration used for authenticating users.
Disable or enable a configured LDAP user directory
Command:
weka user ldap disable
weka user ldap enable
These commands are used for disabling or enabling user authentication through a configured LDAP user directory.
Note: You can only disable an LDAP configuration, but not delete it.
