I suspect that the problem here is that you are using targeted policy,
and targeted policy doesn't deal with user domains. Targeted policy
only tries to confine specific daemons, not users. Hence, you likely
want your auditallow rule to be in terms of unconfined_t rather than
userdomain.
But note that RHEL4 Update ?2? should include enhanced auditing support,
so you shouldn't even need SELinux per se to apply auditing if that is
all you want (i.e. you don't care about mandatory access control).
auditctl and auditd should let you configure your auditing directly
without dealing with SELinux policy.
