GSS-TSIG: Client DDNS update fails, key not found

[#1]

Hello,

This worked fine until I needed to reinstall lab windows servers and now I just cannot get it to work at all..

Any idea what to check?

NIOS 9.0.5, Windows 2019 Server

Why am I getting key not found when clearly there is keytab file present?

syslog:
GSS-TSIG authentication failed for (DNS/ddi01.lab.local@LAB.LOCAL, kvno 5, aes256-cts-hmac-sha1-96): key not found

Infoblox > show dns_gss_tsig keytab
Vno Type Principal Aliases
5 aes256-cts-hmac-sha1-96 DNS/ddi01.lab.local@LAB.LOCAL

Any help appreciated!

Thanks,

AJ

You didn't explicily call this out - when you re-did your Microsoft lab, you completly regenerated the Keytab file for NIOS from scratch?
