The system enforces the rules in a GRANT LOGON or REVOKE LOGON statement according to the host group and user ID clauses in the statement. More specific clauses contained in a current GRANT or REVOKE statement take precedence over any more general clauses from a previous GRANT or REVOKE statement, for example:

    GRANT LOGON ON ALL TO Adam

is superseded by limitation on host ID HGID2:

REVOKE LOGON ON HGID2

if user Adam is assigned to host group HGID2.
