I need Bind so that dynamic dns will work with Linux clients. This was OK in 4.0.5. Any ideas anyone? Provisioning with or moving to BIND9_DLZ produces the error: samba_upgradedns --dns-backend=BIND9_DLZ Reading domain information DNS accounts already exist No zone file /usr/local/samba/private/dns/HH3.SITE.zone DNS records will be automatically created DNS partitions already exist Adding dns-hh16 account Failed to setup database for BIND, AD based DNS cannot be used Traceback (most recent call last): File "/usr/local/samba/sbin/samba_upgradedns", line 454, in <module> domainguid) File "/usr/local/samba/lib64/python2.7/site-packages/samba/provision/sambadns.py", line 805, in create_samdb_copy os.path.join(dns_dir, "sam.ldb")) File "/usr/local/samba/lib64/python2.7/site-packages/samba/tdb_util.py", line 36, in tdb_copy status = subprocess.call(tdbbackup_cmd, close_fds=True, shell=False) File "/usr/lib64/python2.7/subprocess.py", line 493, in call return Popen(*popenargs, **kwargs).wait() File "/usr/lib64/python2.7/subprocess.py", line 679, in __init__ errread, errwrite) File "/usr/lib64/python2.7/subprocess.py", line 1249, in _execute_child raise child_exception OSError: [Errno 2] No such file or directory
