Hi all! I want to recreate my DNS records from scratch and I am unable to find a way to do so. I have tried removing the DC=FORESTDNSZONES and DC=DOMAINDNSZONES ldb files and recreating them with samba_upgradedns but I get the following error: Creating DNS partitions Traceback (most recent call last): File "/usr/sbin/samba_upgradedns", line 356, in <module> dnsadmins_sid) File "/usr/lib/python2.7/site-packages/samba/provision/sambadns.py", line 947, in create_dns_partitions names.configdn, names.serverdn) File "/usr/lib/python2.7/site-packages/samba/provision/sambadns.py", line 239, in setup_dns_partitions "SECDESC" : b64encode(descriptor) File "/usr/lib/python2.7/site-packages/samba/provision/common.py", line 50, in setup_add_ldif ldb.add_ldif(data, controls) File "/usr/lib/python2.7/site-packages/samba/__init__.py", line 224, in add_ldif self.add(msg, controls) _ldb.LdbError: (68, 'ldb_wait: Entry already exists (68)') I have tried with both SAMBA_INTERNAL and BIND9_DLZ both give me the same error. Is there any known method to achieve this? Thanks, Alex
