Principles of LMT Authority Management

This describes the principles of the LMT authority management from the following aspects: user identification, operation authority, and operation time limit.

The LMT supports multi-user operations. To ensure system security, the system performs access control through user identification, operation authority, and operation time limit.

• User identification: The system identifies a user by the user name and password. If the user name and password does not match, the user cannot log in to the system.
• Operation authority: The system classifies the users into levels. The users of different levels are assigned with different functional groups. The system controls the user authority through the operations in the functional groups.
• Operation time limit: The system can control user authority through the configuration of the time limit for user operations.
