After updating to 9.501-5 SSO for HTTP authentication failed and domain join not working.

UTM 9.501-5

Windows server 2012 domain controller.

I installed the 9.5 update on June 2, did not see any issues with this for the client, updated to 9.501-5 on June 12 midnight, and Internet access is failing on multiple sites.

Can get to Google.ca

Cannot get to canada411.com - Too many http redirects message.

Turned off web filtering and the websites were available - but the client requires filtering.

Re-enabled and turned off AD SSO authentication and websites are available again with correct content being blocked.

Attempted to remove from and rejoin domain, but domain join failed.

 

Currently, I have the client functioning, but, I need to rejoin AD and resume SSO authentication.

  • It's a shame that you did not pull the up2date seeing as you have known about this for a while.

    We applied the update on friday and then on Saturday we had the problem.

    I tried searching for the actual error that you get in the log

    Key version number for principal in key table is incorrect

    but your kb article  https://community.sophos.com/kb/en-us/126819  doesn't actually include the error! so I was unable to find it.

    Please can you update it to include this information.

     

    It is nice to see that you tweeted about this on Saturday, (something I have complained about the lack of in the past)  but by then it was too late!
