Because system access by Avaya Services is infrequent yet often required to maintain maximum uptime, do not enable password aging for Avaya services accounts.
Use care in enabling password aging for accounts authenticated through external servers, for example RADIUS accounts, that do not support the user changing a password through the Messaging server. If such a user’s account expires, (Pluggable Authentication Modules) PAM issues a prompt to change the password. If this is not possible through Messaging, then this user is locked out.
