[Samba] samba-tool error messages: what needs fixing most?

[Zombie Ryushu]

I have an error in my Samba Server and I don't actually know what's wrong.

[2022/05/28 08:52:34.671510,  0] ../../source4/auth/unix_token.c:97(security_token_to_unix_token)
   Unable to convert first SID (S-1-5-7) in user token to a UID.  Conversion was returned as type 0, full token:
[2022/05/28 08:52:34.671600,  0] ../../libcli/security/security_token.c:52(security_token_debug)
   Security token SIDs (4):
     SID[  0]: S-1-5-7
     SID[  1]: S-1-1-0
     SID[  2]: S-1-5-2
     SID[  3]: S-1-5-64-10
    Privileges (0x               0):
    Rights (0x               0):

This error is from a few months ago, it's isolated to one Domain controller and everyone has said it's user error, but I cannot understand how.
