18.6.3 Notes on user authentication

When a large amount of login activity is concentrated on a single authentication server, the system might output the message KAVB0109-E, KAVB0105-E, KAVB0106-E, or KAVB0108-E and prevent further login attempts. If this error occurs, wait a while and then retry the login.

For details on these messages, see the manual JP1/Integrated Management - Manager Messages.
When you log in from JP1/IM - View or JP1/AJS - View, spaces after a password are ignored.
