[Samba] Error Upgrading Schema

[Matthew Delfino Samba List]

Rowland,

I had the same thought. When I do that and try again, I get this message:

 # samba-tool domain schemaupgrade
 Temporarily overriding 'dsdb:schema update allowed' setting
 Patched Sch49.ldf using /usr/share/samba/setup/adprep/WindowsServerDocs/Sch49.ldf.diff
 Exception in patch: b'patching file Sch50.ldf\nHunk #2 succeeded at 209 (offset -35 lines).\n'
 b'patch: **** unexpected end of file in patch\n'
 ERROR: Failed to upgrade schema

I feel like it's got to be some small syntax oversight on my part...

Thanks,
Matthew

Indeed, I do have some attributes in that section commented out:

    OK, I think I understand what is going on here, running the command
    'samba-tool domain schemaupgrade' uses 'Schema-Updates.md', but it also
    patches the ldifs created with the *.diff files and these contain
    attributes that you have removed from 'Schema-Updates.md'. This means
    that it is the patching that is failing, so try removing the already
    installed attributes from the *.diff files as well.
