The above is wrong, you are putting everything into a tdb file, I would
expect to also see lines that start 'idmap config xxxxx' and set a
winbind backend

Perfectly acceptable, Samba is just telling you it is closing the
connection, if you don't want the messages, remove the 'log level' line
from smb.conf

I should also point out that, unless you have extended support,
Solaris 10 is EOL. Samba 4.4.x is also EOL, the only supported
versions are 4.7.x, 4.8.x and 4.9.x
