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.
