Hi. I have some machines that I can't log in anymore. I think I changed their accounts to User accounts by mistake. Now pdebedit show the U flag instead W. I tried to change it like this: # pdbedit -c='[W]' machine-211$ Can only set [NDHLX] flags I tried also to recreate one machine account. I removed the account with smbpasswd -x , and added it again, but it won't login. I guess it is because the SID changed. I tried setting the SID again: # pdbedit -U S-1-5-21-64316383-546362030-1349479702-81176 -u machine-214$ Unable to modify TDB passwd: NT_STATUS_UNSUCCESSFUL! Unable to modify entry! - Is there a way to turn those users to machines ? - Can I change that SID somehow ? This is Samba 3.2.5 on Debian Lenny. Thank you very much.
