In /usr/lib64/python2.7/site-packages/samba/provision/sambadns.py
Update: It is failing in create_samdb_copy specifically here:
# Copy root, config, schema partitions (and any other if any)
# Since samdb is open in the current process, copy them in a child
process
try:
tdb_copy(os.path.join(private_dir, "sam.ldb"),
os.path.join(dns_dir, "sam.ldb"))
for nc in partfile:
pfile = partfile[nc]
tdb_copy(os.path.join(private_dir, pfile),
os.path.join(dns_dir, pfile))
Let me try and figure out what his is doing and I'll write some prints to
find out what the culprit is.
