I don't mean to ask really dumb questions, but can you:
cat /etc/passwd
cat /etc/group
grep -F ':503:' /etc/passwd
grep -F ':504:' /etc/group

from within the jail?

If not, you may have directory ownership/permissions problems. For
example, in a jail, make sure /etc o:g=root:root & perm=0551.

I know you said you have checked... but just adding another approach.
