I am using a standalone Samba server on Ubuntu 18.04 (Samba 4.7.6). When an employee leaves the company, their Unix account ist locked (but not deleted). Their Samba account, however, is deleted via smbpasswd -x foo. When viewing the properties of a shared file owned by a deleted user from Windows, the owner is displayed as foo (Unix Userfoo). However, there is one deleted user that is displayed as Account Unknown (S-...). Where does this discrepancy come from and can it be “fixed”? Additionally, I noticed that the last four digits of the SIDs don’t match the Unix UIDs. Is that normal? Side note: the user’s have all been added via smbpasswd -a foo.
