Why can't I access File Sharing when Open Directory is enabled in macOS Mojave?

Here's the procedure I have followed: 1. Install a fresh copy of macOS Mojave to an APFS volume 2. Perform initial OS configuration and create 'admin' user at first launch. Assign a static IP from 192.168.168.0/24 private network. Use a DNS server located in private network. Ensure IP resolves to a FQDN ('test.mydomain.com') and vice versa. 3. Download macOS Server application (5.7) from App Store 4. Open macOS Server application 5. Create a new Open Directory domain with default options 6. Create a new user 'testuser' to Local Network Directory 7. Create a new group 'testgroup' to Local Network Directory 8. Assign newly created 'testuser' to 'testgroup' 9. Open System Preferences application 10. Open Sharing preferences 11. Enable File Sharing 12. Create a Shared Folder 'myshare' and assign 'testgroup' and 'admin' Read&Write access to it 13. Select 'myshare' and click Options button to ensure SMB sharing is enabled for it 14. Attempt to connect to the file server from a client computer within the same subnet via smb://test.mydomain.com/myshare or alternatively smb://192.168.168.X/myshare either using 'admin' or 'testuser' credentials In the last step connection fails for both 'admin' and 'testuser' accounts. If I turn Open Directory to Off, I can connect with 'admin' user. Restarts in any phase of the procedure make no difference. **Why can't I access SMB when Open Directory is enabled?** Here are the opendirectoryd log entries from creating the OD master (step 5): https://pastebin.com/uQm8b8NM Here are the opendirectoryd and smbd log entries from login attempt (step 14): https://pastebin.com/U2RS3LYC & https://pastebin.com/7bFNfd8V
