I can't figure out how to say this, so I'll just show it - I 
*think* this is what you're asking:


root at pkgdev32:~# groupadd -g 300 testgroup
root at pkgdev32:~# useradd -d /dev/null -s /bin/false -u 300 -g 300 testuser
root at pkgdev32:~# touch testfile
root at pkgdev32:~# chown testuser:testgroup testfile
root at pkgdev32:~# ls -lh testfile
-rw-r--r-- 1 testuser testgroup 0 Jun 19 00:13 testfile
root at pkgdev32:~# tar cf test.tar testfile
root at pkgdev32:~# tar tvf test.tar 
-rw-r--r-- testuser/testgroup 0 2013-06-19 00:13 testfile
root at pkgdev32:~# getent group testgroup ; getent passwd testuser
testgroup:x:300:
testuser:x:300:300::/dev/null:/bin/false
root at pkgdev32:~# scp test.tar pkgdev64:.
