Kindly follow up there... https://cygwin.com/ml/cygwin/2016-03/msg00076.htmlSorry, I did not get that answer emailed to me (some confusion during the subscription). I am not clear with answer given by Corinna. The idea behind RFC2307, imho is to have a consistent UID/GID between systems which have joined a domain. This is what we achieved in our domain, where a user login into whatever Linux box, gets the same uid/gid. One would expect the same behaviour in cygwin (on a joined machine), wouldn't he ?That's not the idea behind the uid/gid mapping. You might have noticed that "unix" is not used as a keyword in the passwd and group settings in /etc/nsswitch.conf, only in the db_home, db_shell, and db_gecos settings. Keep in mind that we have two mappings. The main mapping is the mapping between Windows SID and a computed uid/gid value used in Cygwin which allows fast mapping in both directions. A computed value drops the requirement to access an LDAP server for the mapping, which is especially bad when not using AD as mapping server. Please read https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-nfs and https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-samba again. The RFC 2307 mapping only comes into play when reading meta information from an NFS or Samba share. The unix uid/gid values have to be mapped to a Windows user (better: SID) in the first place, not to the Cygwin uid/gid values. The actual uid/gid values are irrelevant. Worse, using the RFC 2307 values might collide with other, computed uid/gid values. Corinna
OK, I noticed that. Now it brings me a problem using rsync on cygwin. On cygwin: $ cat /etc/rsyncd.conf [test] path = /cygdrive/c/tmp comment = zone de test fake super = yes read only = no On the Linux box: # ls -l /home/tunix/ ... drwxr-xr-x 3 tunix root 4096 9 mars 12:23 resto_win -rw-rw-r--+ 1 tunix utilisateurs_du_domaine 82882 9 mars 10:56 tmp.ps # rsync -avz --acls --delete /home rsync://192.168.0.23/test .. # rsync -avz --acls --delete rsync://192.168.0.23/test/home/tunix resto_win/ ... # ls -l /home/tunix/resto_win/tunix/ ... drwx------ 2 1050005 1049089 4096 9 mars 12:14 resto_win -rw------- 1 1050005 1049089 82882 9 mars 10:56 tmp.ps You will notice that owner, group and ACLs are *not* restored properly Am I demanding too much to cygwin ? Thanks for your time. Marc
