About local users
To implement local authentication, authorization, and accounting, create local users and configure user attributes on the device. The local users and attributes are stored in the local user database on the device. A local user is uniquely identified by the combination of a username and a user type.
Local users are classified into the following types:
Device management user—User that logs in to the device for device management.
Network access user—User that accesses network resources through the device.
The following shows the configurable local user attributes:
Description—Descriptive information of the user.
Service type—Services that the user can use. Local authentication checks the service types of a local user. If none of the service types is available, the user cannot pass authentication.
User state—Whether or not a local user can request network services. There are two user states: active and blocked. A user in active state can request network services, but a user in blocked state cannot.
Upper limit of concurrent logins using the same user name—Maximum number of users that can concurrently access the device by using the same user name. When the number reaches the upper limit, no more local users can access the device by using the user name.
User group—Each local user belongs to a local user group and has all attributes of the group. The attributes include the password control attributes and authorization attributes. For more information about local user group, see "Configuring user group attributes."
Binding attributes—Binding attributes control the scope of users, and are checked during local authentication of a user. If the attributes of a user do not match the binding attributes configured for the local user account, the user cannot pass authentication.
Authorization attributes—Authorization attributes indicate the user's rights after it passes local authentication.
Configure the authorization attributes based on the service type of local users.
You can configure an authorization attribute in user group view or local user view. The setting of an authorization attribute in local user view takes precedence over the attribute setting in user group view.
The attribute configured in user group view takes effect on all local users in the user group.
The attribute configured in local user view takes effect only on the local user.
Password control attributes—Password control attributes help control password security for device management users. Password control attributes include password aging time, minimum password length, password composition checking, password complexity checking, and login attempt limit.
You can configure a password control attribute in system view, user group view, or local user view. A password control attribute with a smaller effective range has a higher priority. For more information about password management and global password configuration, see "Configuring password control."
Validity period—Time period in which a network access user is considered valid for authentication.
