csync2 replicates numerical uid/gid.
that has always been that way.
If you find someone to write a "by name" feature,
we are happy to take it.

when authenticating against /etc/passwd and friends,
you may want to put that into csync2 as well.
otherwise, you have "centralized" authentication anyways (ldap or
similar), and the id <-> name mapping is already covered.
