Hello, I'm running a Samba 4.3.3 install on FreeBSD 8.4 (ZFS) in domain mode with passdb tdb backend. The databases and config files are the current versions of an install that I think started in the 1.9.x version range back in the late 90s (I can't remember exactly--it's been a long time!) and smbpasswd days. I'm now trying to convert to an AD install using the classicupgrade tool, following the wiki instructions, and am receiving a ProvisioningError at the very end of the script. This the error message: ERROR(<class 'samba.provision.ProvisioningError'>): uncaught exception - ProvisioningError: Could not add member 'S-1-5-21-197568832-424389326-1147915938-2604' to group 'S-1-5-21-197568832-424389326-1147915938-515' as either group or user record doesn't exist: Unable to find GUID for DN I can't find member S-1-5-21-197568832-424389326-1147915938-2604. It does not show up in the output of "pdbedit -Lv". Where else, or how else, should I be looking? The group (-515) is my domain machines group. Here's my command line: samba-tool domain classicupgrade --dbdir=/var/db/samba4.PDC/dbdir/ --use-xattrs=yes --realm=my.newrealm.com/usr/local/etc/smb4.PDC.conf Everything looks good until the very end: --------------------------------- [snipped first part...] Setting up sam.ldb rootDSE marking as synchronized Fixing provision GUIDs A Kerberos configuration suitable for Samba 4 has been generated at /var/db/samba4/private/krb5.conf Setting up fake yp server settings Once the above files are installed, your Samba4 server will be ready to use Admin password: a_,FVAuUobIFhEwI9%Z<!Hn2,C%97B Server Role: active directory domain controller Hostname: fileserver NetBIOS Domain: OLDDOMAIN DNS Domain: my.newrealm.com DOMAIN SID: S-1-5-21-197568832-424389326-1147915938 Importing WINS database Importing Account policy Importing idmap database Cannot open idmap database, Ignoring: [Errno 2] No such file or directory Adding groups Importing groups Group already exists sid=S-1-5-21-197568832-424389326-1147915938-512, groupname=Domain Admins existing_groupname=Domain Admins, Ignoring.
