[Samba] Classic Upgrade changes domain SID

Sun Aug 27 10:56:28 UTC 2023

Dear Rowland:

Thanks for the quick response

> Can you please post the command that you used to carry out the classic

here's what I did:

1) Old WORKGROUP is NAV, old NETBIOS NAME is SERV00,
old fqdn is v480.naev.de, so I decided to use:
- new domain = NAV
- new realm = NAV.NAEV.DE
- new netbios name = NS1 (or SERV00)
- fqdn of new server = ns1.nav.naev.de (or serv00.nav.naev.de)

2) removed ISO-8859 special characters from users fullnames

3) delete group mappings for windows standard groups (in particular
Domain Admins)

4) Copied smb.conf, secrets.tdb, schannel_store.tdb, passdb.tdb,
group_mapping.tdb,
account_policy.tdb, /etc/passwd, /etc/group from old server to /var/samba/NT4-DC
directory of new server

5) created all samba-related user-accounts, groups and groupmappings with:
(awk -F: '$3>=200 && $3<60000{print "groupadd -g",$3,$1}'
/var/samba/NT4-DC/group | sort
 awk -F: '$3>=500 && $3<20000{g=$4;if(g==65534)g="nogroup"; print
"useradd -u",$3,"-g",g,"\x27"$1"\x27"}' /var/samba/NT4-DC/passwd |
sort
 awk -F: '$3>=200 && $3<60000{split($4,a,",");for(i in a) print
"usermod -aG",$1,a[i]}' /var/samba/NT4-DC/group
) | sh

6) replaced SERV00 by the netbios name of the new server (i.e. NS1) in
/var/samba/NT4-DC/smb.conf

7) Started classic upgrade:
cd /var/samba
kill `cat /var/samba/run/samba.pid`
rm -rf private/* smb.conf log.* sysvol
/usr/samba/bin/samba-tool domain classicupgrade \
  --dbdir=/var/samba/NT4-DC/ \
  --realm=NAV.NAEV.DE \
  --dns-backend=SAMBA_INTERNAL \
  /var/samba/NT4-DC/smb.conf

Here's the output:

One more thing: The new domain SID is different from the old one.
But it does not even start with S-1-5-21 !!!
