[Samba] samba 4.8 with bind - bugged dns entry in reverse lookup zone

[Kacper Wirski]

Thank You for the prompt reply.

By "sam.ldb" you mean the samba/bind-dns/dns/sam.ldb right?

After executing:

ldbsearch --cross-ncs -H /path/to/samba/bind-dns/dns/sam.ldb '(name=49)'

I do find same records, as with previous search including the one I need 
to delete as it is bugged.

It's dn is:

DC=49,DC=1.168.192.in-addr.arpa,CN=MicrosoftDNS,DC=DomainDnsZones,DC=mysubdomain,DC=mydomain,DC=com

But when executing search again with '(dn=...)' instead of '(name=...)':

ldbsearch --cross-ncs -H /path/to/samba/bind-dns/dns/sam.ldb 
'(dn=DC=49,DC=1.168.192.in-addr.arpa,CN=MicrosoftDNS,DC=DomainDnsZones,DC=mysubdomain,DC=mydomain,DC=com)' 


I get "0 records found".

I suppose there's something wrong with my query. i tried escaping "=" 
after dn= (e.g. dn=DC\=49 etc.), but it didn't work. So what am I missing?

And what would be proper syntax for ldbdel:

ldbdel -H /path/to/samba/bind-dns/dns/sam.ldb '(dn=<corrected dn from 
above)'

?


Regards,

Kacper
