I would remove it, Samba creates it by default without it being in smb.conf.

OK, then I suppose I should inform you that they are now deprecated and
will be going away. There is also the problem that smbldap-tools is no
longer maintained, it doesn't even have a valid website. I suggest you
start making plans to upgrade to AD.

Hopefully stopping apparmor may cure your problem

You are already using the log level I would start at. If you are
struggling to understand the logs and are willing to do so, send me the
samba logs, you can sanitise them if you like.
