GSS-TSIG and provides more granular update security policies than Windows Server DNS can support natively, including update policies that specify which GSS-TSIG attributes to identify update clients by, and explicit controls on which record types that client can update. This improved granularity allows deeper

The method for distributing public keys as a DNS resource record (RR) is specified in RFC 2930, with GSS as one mode of this method. 2014-03-27 · Microsoft Windows software does not support TSIG via hmac-md5, rather Microsoft has implemented a different mechanism for authenticating servers using GSS-TSIG. 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.

I figured maybe https://github.com/jcmturner/gokrb5 could be useful to do the Kerberos side of things. The GSS-TSIG process is not as stable as we would like.

GSS-TSIG (Generic Security Service Algorithm for Secret Key Transaction) is used to authenticate DDNS updates. 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."

GSS-TSIG involves a set of client/server negotiations to establish a "security context." Specifies the Generic Security Service Algorithm for Secret Key Transaction Authentication for DNS (GSS-TSIG) Protocol Extension, which identifies one possible extension to TSIG based on the Generic Security Service Application Program Interface (GSS-API).

It is an extension of TSIG authentication that uses the Kerberos v5 authentication system.

tkey-max-exchanges - Per recommendation from RFC 3645 to prevent endless looping, the DNS server shall impose a maximum number of TKEY exchanges (i.e.

When creating a Zone on a DNS server there is an option to enable or disable DNS Dynamic Zone Updates. Specifies the Generic Security Service Algorithm for Secret Key Transaction Authentication for DNS (GSS-TSIG) Protocol Extension, which identifies one possible extension to TSIG based on the Generic Security Service Application Program Interface (GSS-API). This page and associated content may be updated frequently. The show dns_gss_tsig commands provide information about an Infoblox DNS server that is configured to receive GSS-TSIG authenticated DDNS updates from a DHCP server. You can use these commands for diagnostic purposes and to troubleshoot issues.

Uppdateringen säkras med GSS-TSIG. IP-adressen för IPA-LDAP-förbindelsen används för uppdateringar, om det inte specificeras på annat sätt med 

Zones now can be updated via transactions. A new zone subclass, dns.versioned.Zone is available which has a thread-safe transaction implementation and support for keeping many versions of a zone.
