Can you add --show-binary flag to ldbsearch to decode dnsRecord attribute?
Also, more interesting would be to check the security descriptor for this record
as that would tell us how this particular record was created.
ldbsearch -H /usr/local/samba/private/sam.ldb
That will show the security descriptor. And if you want to decode the SDDL
format you can add --show-binary.
I am interested in finding out the owner of the record as that will tell how
this particular record was created.
