User and Connection Management
In Ultra Secure Mode (ULTRA_SECURE_MODE=YES), Users can be automatically disabled or locked out
by the system when they do not log into the Collaboration Server application for a predefined period or if
their login session does not meet Enhanced Security requirements. Users can be manually disabled by the
administrator.
An administrator can enable a User who was disabled automatically by the system (in the Ultra Secure
Mode) or manually by the administrator.
Additional security measures can be implemented in the Collaboration Server by setting the appropriate
system flags. These measures control the system users, the user connections to the MCU and the user
login process.
Managing system users includes:
● User types that are not supported when the Ultra Secure Mode is enabled.
● Disabling and enabling system Users.
● Renaming Users.
● Disabling inactive users.
Managing the user login process includes:
● Implementing Strong Passwords.
● Implementing password re-use / history rules.
● Defining password aging rules.
● Defining password change frequency.
● Forcing password change.
● Conference and Chairman Passwords.
