https://community.sophos.com/utm-firewall/f/management-networking-logging-and-reporting/92190/fallback-log-filling-with-kinit-failed-client-not-found-in-kerberos-databaseHi. My fallback log is constantly filling with messages like this: 2017:05:19-08:40:18 portal [daemon:err] winbindd[25866]: [2017/05/19 08:40:18.792234, 0] libsmb/cliconnect.c:1865(cli_session_setup_spnego) 2017:05:19-08:40:18 portal [daemon:err]en-USTelligent Community 12https://community.sophos.com/thread/333873?ContentTypeID=1Sat, 20 May 2017 15:23:54 GMT4be5eb7d-caa4-4ff5-8e60-8f9463545a35:e550b92b-3058-4f92-98e8-4d691c73e489BAlfson<p>Hi Andrew,</p> <p>I googled <em>site:community.sophos.com/products/unified-threat-management/f Kinit failed -succeeded</em></p> <p>The thread that caught my eye indicated that this might be solved by un-joining and then re-joining the UTM to the domain.&nbsp; Un-join by using incorrect credentials and then join again using valid credentials.&nbsp; If that didn&#39;t work, you might need to rename your UTM using only lowercase letters before joining again - see The Zeroeth Rule in <a href="/products/unified-threat-management/f/general-discussion/22065/rulz">Rulz</a>.&nbsp; Any luck with either approach?</p> <p>Cheers - Bob</p><div style="clear:both;"></div>
