BUG.(CHK,NOACTF,JSYSA,SOFT,<No account database - account validation disabled>,,<
Cause: An account is to be validated because account validation is enabled,
but no account database has been loaded. It would appear that account
validation was turned on (possibly with the ENABLE ACCOUNT-VALIDATION
command in SYSTEM:n-CONFIG.CMD) without putting an account database in
BS:<SYSTEM>ACCOUNTS-TABLE.BIN.
Action: Account validation has been disabled. Either turn off account
validation by editing SYSTEM:n-CONFIG.CMD or install an account
database in BS:<SYSTEM>ACCOUNTS-TABLE.BIN with the ACTGEN utility.
