Users can be created and defined at the server level, meaning that they are shared between all the projects. But you can also create users specific to your site that are not available for other projects. You can manage these users from Administration>Site>Users .
You can create users that are specific to your site.
To create a site user:
You can import users into Jahia in batches using a CSV file. In the CSV file, each user record must contain at least a username and a password, but may contain all properties for a user. The CSV fields must be specified in a header such as this one.
j:nodename,j:password,j:firstName,j:lastName
steven,steven1234,Steven,ACME
robert, robert1234, Robert, ABME
To batch import users:
To edit to user’s properties:
You can remove users that you no longer need.
To remove a user:
The user is removed from the system.
You can lock a user account to disable their account and prevent them from logging in. Locking an account is useful because it blocks the user without deleting their account and all information, documents and contents in their personal directory.
When an account is blocked their session is immediately terminated.
To lock a user:
Edit Roles and Live Roles can be assigned to users or groups in Content Editor on a specific node (page, content item, and more). The permissions associated with the role are then conferred to the users and the members of the designated groups. For more information, see Specifying advanced options in Content Editor.
External user and group providers Jahia allows a connection between a specific website and an external group provider (for example, LDAP). First, ask your current server administrator to connect Jahia with the external user provider you want to have access to. When the connection is made, the server administrator has to link it to your website through the target site field. When this is done, you will find all the users and groups from this external provider into your Users entry in the site administration.
