Thanks for your help. The reason I ask these questions is a little bit
out of curiosity. I also have some users that already exist in the my
smbpasswd but since my smbd now uses LDAP to store the passwords I
needed to know what the consequences of just giving these users a new
rid(sid) where. I think I would have to stop the samba server and start
the old one to extract the rid. But since this server is in a production
environment I hoped that it would be possible just to give the users a
new rid instead.
