Hello. We're in the process of migrating an old Samba3 domain to Samba4. Everything is (seem to be?) going ok in our test migration, but we're finding this issue when running samba-tool dbcheck --cross-ncs Checking 15131 objects ERROR(<class 'IndexError'>): uncaught exception - index out of range File "/usr/local/samba/lib/python3.6/site-packages/samba/netcmd/__init__.py", line 186, in _run return self.run(*args, **kwargs) File "/usr/local/samba/lib/python3.6/site-packages/samba/netcmd/dbcheck.py", line 170, in run controls=controls, attrs=attrs) File "/usr/local/samba/lib/python3.6/site-packages/samba/dbchecker.py", line 259, in check_database error_count += self.check_object(object.dn, attrs=attrs) File "/usr/local/samba/lib/python3.6/site-packages/samba/dbchecker.py", line 2435, in check_object elif obj[attrname][0][1] == b'\x00'[0] and obj[attrname][0][2] == b'\x00'[0] and obj[attrname][0][3] == b'\x00'[0] and obj[attrname][0][4] != b'\x00'[0] and obj[attrname][0][5] == b'\x00'[0]: We're running Ubuntu 18.04.3 LTS with samba 11.4.6. but this also happens with samba 11.4.0 Any ideas? Is this normal or should we be looking for more errors?
