samba - Apr 2022 - Failed to convert SID to a UID

Hi Team,

I see messages in the logs on my smbserver like:

smbd[15370]: [2022/04/14 14:32:56.556685,  0]
../../source3/auth/auth_util.c:1928(check_account)
smbd[15370]:   check_account: Failed to convert SID
S-1-5-21-3042323961-424325435-1432587418-1234 to a UID
(dom_user[SAMDOM\computer01$])

I am using rfc2307 idmapping and computer accounts were never assigned a
uidNumber and a gidNumber (simply because I never figured they would need
one). Surely that is causing the error message.

The question is: is this a problem that disrupts something in the
communition between windows 10 and the fileserver or can I ignore the
message?

My fileserver and DC servers run Samba 4.15.6 on Bullseye.

It isn't so much an error message as a note.

Your 'user' is actually a computer 'computer01$'.

This will not disrupt anything and you can ignore the messages.
