samba - Sep 2016 - upgrade 4.4 -> 4.5 broke standalone server smbmount of drives?

All,

  I've run samba in standalone mode since the 2.0.7 days and have been
though a
few breakages due to version updates along the way. It seems we have hit one
again in the 4.4 to 4.5 update. Specifically, the update was

samba-4.4.5 => samba-4.5.0

  There were no changes made to smb.conf, but the following attempted mount
failed using:

mount.cifs //phoinix/samba /mnt/phx -o
username=david,uid=1000,credentials=/home/adm/mountcfile,noperm

  There are no entries in the logs telling me why the mount fails, it just
fails. Were there new share connection requirements put in place in 4.5?

Please send debug level 10 logs of smbd.
