No, this is not "expected". The "passwd.byname" lookup result is exactly
the result of the C-library getpwnam(3). If this is not working, that's
the problem. The output of

getent passwd user
and
postmap -q user unix:passwd.byname

must be the same, or the underlying system is broken in some fashion.
The example below shows the two commands producing *identical* output,
hence a count of "2" from "uniq -c":

$ (getent passwd viktor
postmap -q viktor unix:passwd.byname) |
sort |
uniq -c |
awk '{print $1}'
2

The tests must be done as a non-root user to make sure that file
permissions don't restrict getpwnam(3) to the super-user.
