The ACF00149 is the result of specifying a password that contains a reserved word prefix that is not allowed.
This is controlled by the ACF2 GSO PSWD PSWDRSV|NOPSWDRSV and PSWDRSVW|NOPSWDRSVW settings in conjunction with the ACF2 GSO RESWORD list of reserved words.
Details on GSO PSWD PSWDRSV|NOPSWDRSV and PSWDRSVW|NOPSWDRSVW:
