CAP_AUDIT_CONTROL in RHEL4

I've got my own process listening directly for audit events on the netlink interface. I'd like to drop its privileges for normal operation. However, under certain circumstances it has to enable or disable auditing, which requires CAP_AUDIT_CONTROL. I can't work out how to create a cap_t with this capability. I've tried: cap_from_text("CAP_AUDIT_CONTROL=pe") and cap_from_text("cap_audit_control=pe") and cap_from_text("30=pe") However in all cases I get EINVAL. What am I doing wrong?
