Hi, I have to migrate a company from Samba3+LDAP to Samba4. This company has different locations (around 10), all of them have the same LDAP tree replicated with its Samba server running as PDC. The user/group/passwd part of the migration is solved, but I have to deal with machine account yet. My plan is the following: First, install the Samba DC in the central location, run the classicupgrade. Then, on each location, install the SambaDC, join to the central DC and sync the machine accounts passwords. I need to sync machine passwds because I'm going to migrate one location per week, so the passwords sync'ed in the classicupgrade will outdated by the time a new building is migrated. I was thinking about inyecting the machine password from the old LDAP to Samba4, but I haven't found how to do it yet. Can I inyect the password using LDAP in Samba4? Or using Python passdb module is better? Ideas? Regards, Diego -- Diego
