Dear friend!
When a U2000 server is connected to multiple clients, you need to reset Setting the Maximum Number of Sessions
A user can log in to the U2000 server on multiple terminals. The user can also start multiple U2000 clients on the same terminal to log in to the U2000 server. Setting the maximum number of user sessions limits the total number of sessions that a user can create on multiple login terminals.
User groups are categorized based on user roles. To balance the access attempts of different user roles, you can set the maximum number of user group sessions to limit the total number of sessions that the users in a user group can create on all the login terminals.
The settings of the maximum number of user sessions and user group sessions are limited by the system login mode. If the current system login mode is the single-user login mode, only the admin user is allowed to log in to the U2000 from one U2000 client to set the maximum number of user group sessions and user sessions.
In the LDAP or RADIUS authentication mode, the value of the Maximum number of online users for remote users is 1 by default and can be modified.
The configuration methods are as follows:
1. You have created a user group or user
a. Choose from the main menu (traditional style); alternatively, double-click Security Management in Application Center and choose from the main menu (application style).
b. In the NMS User Management navigation tree, expand the User Group or User node.
c. Select a user group or a user, on the Details tab page in the right pane, set Maximum sessions for the user group or Maximum number of online users for the user.
2. You are creating a user group or user
Set the maximum numbers of user group sessions and user sessions by following the procedures provided in Creating and Authorizing U2000 User Groups and Creating Users and Adding Them to User Groups.
Thank you!
