samba - Mar 2019 - Resetting permissions on transferred files

Rowland,

Thanks for your response.  That's the issue, I'm not sure what other 
details I can give that would be helpful in this situation!  How do I 
identify who owns what and how do I propogate this over?  I'm aware how 
to do chmod/chown and find out the uid for Linux users, but I'm not sure 
how it works for Samba - does Samba use the same uid as Linux users, or 
does Samba retain its own list?  It's the exact same server setup as I 
previously discussed.

Looking up pdbedit -L -v gives the following values for my username (kit):

Old server:
Unix username:        kit
NT username:
Account Flags:        [U          ]
User SID: S-1-5-21-3690213834-1721161859-1610588051-1116
Primary Group SID: S-1-5-21-3690213834-1721161859-1610588051-513

New server:
Unix username:        kit
NT username:
Account Flags:        [U          ]
User SID: S-1-5-21-456595659-2484967225-2845901235-1104
Primary Group SID: S-1-5-21-456595659-2484967225-2845901235-513

As you can see, both SIDs don't match.  how do I synchronise the two?  
I'm happy to do it manually, there's only 5 users.

Many thanks!

With kind regards - Piers

That explains it a bit further, Samba (and Windows) uses the SID to
identify the domain, so user 'kit' with the SID-RID of
S-1-5-21-3690213834-1721161859-1610588051-1116 isn't the same user as
'kit' with the SID-RID of S-1-5-21-456595659-2484967225-2845901235-1104

That is from a Windows perspective, how Unix treats them depends on
how you are using Samba, so I think it is time we saw your smb.conf, so
please post it.
