log.smbd repeatedly show this message:
[2022/12/19 01:02:03.123456, 0] ../../source3/auth/auth.c:441(load_auth_module) load_auth_module: can't find auth method guest!
Check if the samba parameter “
auth methods” has been explicitly configured
testparm -s --parameter-name="auth methods" 2>/dev/null
e.g. via this UCR variable:
ucr search "samba/global/options/auth methods"
If it shows the value
guest then replace it by
anonymous, e.g. by running
ucr set samba/global/options/"auth methods"="$(ucr get samba/global/options/"auth methods" | sed s/guest/anonymous/)"
And then reload the samba configuration by running
smbcontrol all reload-config
This is a per host solution and needs to be checked/repeated on each system running samba, where the samba parameter “
auth methods” has been explicitly configured. If this has been done via UCR policy, the policy should be checked and adjusted accordingly.
