The LogonRules view is used to review the rules generated by the GRANT LOGON and REVOKE LOGON statements. These statements define which user can log on from what mainframe or LAN host connection, and whether the logon string of the user is acceptable without a password.
The initial default is that all users may logon from all hosts, and that every logon string must contain a password. To change the default, use the GRANT LOGON and REVOKE LOGON statements.
