Which PTF added the new RADIUS factors?
SafeNet RADIUS, generic RADIUS, and RSA SecurID RADIUS.
The PTF that introduced RADIUS support was RO98716. The PTF in question is SO00132. A recent PTF for RADIUS MFADATA (tag data) correction is SO00250. With all three of these APARS applied --- you are good to go for the Top Secret side.
In addition to Top Secret maintenance, any MFA authentication service requires either: CA Advanced Authentication for Mainframe (AAM) installed and configured; or IBM's Multi-factor Authentication (MFA).
If you are using CA's AAM, the PTF's require are: RO97949.
If IBM MFA: SO00132 (TSS PTF)
