httpd auid = -1

I’ve noticed that the httpd process on a CentOS 7.7 system I am working with is running with an Audit ID of -1. Example ID values are: auid=4294967295 uid=48 gid=48 ... So if use the standard filter "-F auid!=-1” in the audit rules I do not see httpd activity. Is this common? How do I change the auid to something else, so I can capture the httpd activity in the audit log? Example audit line: type=SYSCALL msg=audit(1596065566.721:31357): arch=c000003e syscall=2 success=yes exit=15 a0=55a0a2d9b3c0 a1=80000 a2=0 a3=7ffe5d4d6720 items=1 ppid=1130 pid=1253 auid=4294967295 uid=48 gid=48 euid=48 suid=48 fsuid=48 egid=48 sgid=48 fsgid=48 tty=(none) ses=4294967295 comm="httpd" exe="/usr/sbin/httpd" key=(null) Thanks, Todd
