Hello and thank you for taking the time to file this bug report. According to the bug description you are running Ubuntu 14.04 on your samba server machine. This release reached its end of life on April 30, 2019 and it is not supported anymore. Is it possible for you to check if the same problem happens when using Ubuntu 18.04 (the current LTS release)?
While waiting for more information I'm setting the status of this bug to Incomplete. Please set it back to New after commenting back and we'll look at it again. Thanks! ** Changed in: samba (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1864853 Title: netbios name directive causes permission errors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1864853/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
