[Samba] Problems with migrating users and groups with classicupgrade

[Robert Moskowitz]

I am assuming that I need to migrate my users and groups if I expect to 
move my user profiles.

Migrating computers is a second question.  But on with details.

My current setup is a ClearOS server running as a PDC.  I get the 
following information from it:

# wbinfo -u
winadmin
guest
rgm
abba
imma
guest2
superrgm

After running:

samba-tool domain classicupgrade --dbdir=/root/samba.PDC/dbdir/ 
--use-xattrs=yes --realm=HOME.HTT --dns-backend=BIND9_DLZ 
/root/samba.PDC/etc/smb.conf

and getting all the services running here I get:

# wbinfo -u
administrator
dns-homebase
dhcpduser
krbtgt
guest

So what went wrong?  Why did not my users make it through the 
migration?  I am attaching the output of the upgrade.  I have already 
changed the password, so don't yell at me for not blanking that out.

# samba-tool domain classicupgrade --dbdir=/root/samba.PDC/dbdir/ 
--use-xattrs=yes --realm=HOME.HTT --dns-backend=BIND9_DLZ 
/root/samba.PDC/etc/smb.conf
