The SAFDEF to ignore the RACROUTE FASTAUTH call for ISF.CONNECT resource is needed to fix ISF458E Not authorized to connect to the SDSF server error when SDSF is using internal security based on ISFPARMS.

The SECTRACE can be run to verify RACROUTE call for ISF.CONNECT resource is getting SFR/RFR=8/8:0 and the ISF458E message.
