porting test suite ( testing audit system ) from RHEL 3 to RHEL 4

Hi all, I want to port the LTP test suite, linux_security_test_suite_EAL3.tar.gz (available from http://ltp.sourceforge.net/EAL3.RHEL.html) from RHEL 3 to RHEL 4. The major issue is porting of laus_test directory, which tests the underlying audit system and the audit system has undergone a substantial change from RHEL 3 to RHEL 4. I plan to change the directory laus_test, which tests LAuS on RHEL 3 to something like, audit_test, which will test the current audit system (on RHEL 4). And for that, I need to change each and every single file in the directory laus_test. I am unable to find any detailed document on the new audit system. Any pointers will be really appreciated. Thanks in anticipation. Vikas
