Hallo Holger,

Wie hast du den migriert?
Da dies unsere Service-Firma gemacht hat, kenne ich nicht alle Details.
Per NFS?
Per Backupplatte?
per NAS
Welches Dateisystem hatte die?

Und jetzt müssen wir herausbekommen, wo die Rechte falsch sind.
Dazu betrachten wir zwei Ebenen:
1) samba: poste mal bitte deine /etc/samba/smb.conf und die
/etc/samba/smb.conf.shares
------------schnip ---------------smb.conf--------------------

   # Windows Internet Name Serving Support Section:
   # WINS Support - Tells the NMBD component of Samba to enable its WINS Server
      wins support = yes

   # WINS Server - Tells the NMBD components of Samba to be a WINS Client
   # Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
   ;   wins server = w.x.y.z

   # This will prevent nmbd to search for NetBIOS names through DNS.
       dns proxy = no

   # that connects

   # parameter to 'yes'.
   ;   syslog only = no

   # We want Samba to log a minimum amount of information to syslog. Everything
   # should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
   # through syslog you should set the following parameter to something higher.

   ####### Authentication #######

   # package for details.
