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.

This is because they are handled differently. They are in an acct field rather 
than auid field.
