I've seen a few discussions on this mailing list about using mod_waklog, particularly regarding x86_64. I've recently had the chance to spend some time looking at it and now have it working on RHEL6 for both i386 and x86_64.
I took the latest code from the git repository (details at http://www.modwaklog.org/download.php) and started by applying the 3 patches from http://userpages.umbc.edu/~aaronk/waklog/ which have been mentioned on this list before. To get it working with Kerberos 1.8 and newer without globally setting the allow_weak_crypto option to true I had to add a call to krb5_allow_weak_crypto() in mod_waklog.c, I think this could be done better as the code now won't work on machines with older versions of Kerberos. I also had to modify the set of libraries which are linked against so that only libafsrpc and libafsauthent are used. I've attached the two small patches required. Cheers, Stephen
