[Samba] backup / restore question

[mourik jan heupink - merit]

Hi all,

I am  following https://wiki.samba.org/index.php/Backup_and_Recovery to 
create backups of my wheezy DC's.

On SysVol we need the extended ACLs, and we need to backup those as 
well. The source4/scripting/bin/samba_backup script does not do this, 
since wheezy's tar doesn't seem to understand --xattr. :-(

So, now I installed metastore to create a dump of the metadata, 
including xattr, and we're getting the following error:

getgrgid failed for ./sysvol: gid 3000000 not found

Searching my AD for gid 3000000 doesn't give anything, and it's also not 
defined in my member server's smb.conf idmap config.

Can anyone explain where gid 3000000 comes from..?
