I'm looking at a problem that has me really scratching my head.
I've got a rhel 5.4 system that's using likewise and active directory to
authenticate users, at least ones that are not defined locally. Locally defined users
work just fine, but any user that is defined in the active directory server is showing up
in events as "unknown(uid)" the uid appears to be filled out correctly, and if
the user is defined locally as well as in active directory it works just fine, but that
kind of defeats the purpose. Also failed logins are showing up correctly, but I can't
figure out what they have done to their system to cause this. Can anyone give me a little
direction on where I should look to determine what's actually going on. I haven't
been able to determine how the system actually resolves the user names.
Don't know if this is important but we are using the prelude plugin and where we
notice the discrepancy is in the output from the prelude-manager, I have not looked to see
if it's wrong in the aureords.

Ausearch/report/libauparse all use the glibc function, getpwuid(). So, the
names would need to be available via that function. That said, there are ways
to hook it up so that it resolves with NSS or nscd. It would seem like more
than just ausearch would have problems resolving user names since getpwnam and
getpwuid are central to almost all Linux programs that display uid or names.
Also failed logins are showing up correctly,
This is because they are handled differently. They are in an acct field rather
than auid field.
