This informational message is sent to the security console when a job is received from an unknown user on a trusted node. The NODES profile lookup for this submitter resulted in a UACC that allowed propagation of the NJE unknown user, set by SETROPTS JES(NJEUSERID(userid)). Propagation of this submitter is not possible. This situation can occur when a job is sent across nodes by an external physical reader such as a card reader. See z/OS Security Server RACF Security Administrator's Guide for details on the NODES profile lookup. This message occurs only once for each IPL; however, an SMF record is cut for every occurrence.
