Description Björn Jacke 2022-05-12 05:41:15 UTC
An AD joined Samba member server, where "map to guest = bad user" is set and an invalid AD account tries to log in, then map to guest does not work, see also:

(In reply to Björn Jacke from comment #0)

Closing this because:

A) It was 'bad uid' in the mailing list discussion.

B) I works for me, whether I use 'bad user' or 'bad uid'

In smb.conf on the server:
    map to guest = Bad Uid

    path = /srv/acl1
    read only = no
    guest ok = yes

I had to set 'map to guest = Bad Uid' instead of 'map to guest = Bad User' on the client, because smbclient kept using the latter (and it worked).

rowland@devstation:~$ smbclient //server/acltest1 -U bjorn
Password for [SAMDOM\bjorn]:

smb: \> 

There is no user called 'bjorn' anywhere in my network.
