[global]

workgroup = S3I
client signing = yes
client user spnego = yes
kerberos method = secrets and keytab
realm = S3I.ORG
security = ads

The above smb.conf works fine with 18.04.

thank you

Hi Mark,

It looks like you have a typo in your config file:

    client user spnego = yes

This should be:

    client use spnego = yes

https://www.samba.org/samba/docs/current/man-html/smb.conf.5.html#CLIENTUSESPNEGO

[mark wehner (mwehner)]

Updated the /etc/samba/smb.conf and still have the issue.

Also comment the config one line at a time, the line that causes the issue is the security = ads. This specified in https://help.ubuntu.com/lts/serverguide/sssd-ad.html.en.

Even if I comment out the security line then smb will start, but sssd will fail
