For this reason, it is not possible to configure a Windows Server running the Microsoft DNS service to perform zone transfers from a server running BIND DNS configured as a master authoritative server with TSIG protection on the allow I know you guys are currently working through the GSS-TSIG portions but I think you're working towards doing the actual update afterwards. Be aware that Windows 2012, both the DNS server and clients, seem to be insanely picky about the compression used in both the TKEY/TSIG exchange as well as actual update. To enable GSS-TSIG signed updates: 1. Go to Grid DNS Properties and under Toggle Advance Mode, click the GSS-TSIG tab. 2. Select Enable GSS-TSIG Authentication of clients. 3.
GSS-TSIG - What does GSS-TSIG stand for? RFC 3645 GSS-TSIG October 2003 the same time, in order to guarantee interoperability between DNS clients and servers that support GSS-TSIG it is required that - DNS servers specify SPNEGO mech_type - GSS APIs called by DNS client support Kerberos v5 - GSS APIs called by DNS server support SPNEGO and Kerberos v5.

First, we have to configure the BIND on our DNS server to use GSS-TSIG for authenticating dynamic updates: /etc/named.conf must contain this: Microsoft Windows software does not support TSIG via hmac-md5, rather Microsoft has implemented a different mechanism for authenticating servers using GSS-TSIG. Microsoft Windows software does not support TSIG via hmac-md5, rather Microsoft has implemented a different mechanism for authenticating servers using GSS-TSIG. GSS-TSIG (Generic Security Service Algorithm for Secret Key Transaction Authentication for DNS) is defined in RFC 3645.

It is a modified form of TSIG authentication that uses the Kerberos v5 authentication system. GSS-TSIG involves a set of client/server negotiations to establish a "security context." It mak GSS-TSIG (Generic Security Service Algorithm for Secret Key Transaction) is an extension to the TSIG DNS authentication protocol for secure key exchange.

TSIG¶. TSIG, as defined in RFC 2845, is a method for signing DNS messages using shared secrets.Each TSIG shared secret has a name, and PowerDNS can be told to allow zone transfer of a domain if the request is signed with an authorized name. The show dhcp_gss_tsig commands provide information about an Infoblox DHCP server that is configured to send GSS-TSIG authenticated DDNS updates to an AD integrated DNS server. You can use these commands to verify your configuration and troubleshoot …
RFC 3645 GSS-TSIG October 2003 Specifically, Section 4.2 of RFC 2845 MUST be modified as follows: Replace: "The server MUST not generate a signed response to an unsigned request." With: "The server MUST not generate a signed response to an unsigned request, except in case of response to client's unsigned TKEY query if secret key is established on server side after server processed client's query.
