HOW to prevent DNS resolver from going into revert lookup (record of PTR type)?

[Lev Olshvang]

Hi Linuxers,

I am jumping on today's DNS thread,

My Linux Debian  uses DNS service some Windows server.

Linux resolver  gets back  IP address ( type A and AAA records), but fail to get back PTR record.
( I am observing DNS queries and failures with Wireshark)

This  cause ldap to use address instead of  host name in  authentication realm and fail.
When I add address -hostname pairs in /etc/hosts,  ldap succeeds. (it uses name in the realm claim)



I did not yet find a way to change nsswitch.conf to some resolver that prevents reverse lookup,
Please give me some ideas if it is possible.


Lev.
