Strange issue with Sophos UTM Web Protection

Hi,

Firstly, I have got to admit, getting here was quite a challenge. It would appear that the Astaro forums have gone now, and this is it's replacement. I can't say that my experience from this new replacement has been good, the overall feel to this isn't very user friendly, just my opinion. Good were the days where you could easily log-on to a forum and start a new thread, where as now, with this replacement, you have to work out how to actually log-on and then join a group before you can create a question... what?!!

Going off topic here, I'll get to the reason why I am here today. For a while now, I have had an intermittent issue with Web Protection and Active Directory SSO authentication, where all web access is blocked. This occurrence only occurs after either a restart of the Sophos UTM or by a restart of ALL domain controllers. This issue only affects devices which use a profile with Active Directory SSO authentication set as the default. I have discovered that when this issue occurs, if I simply visit the eBay website, all web access is restored. If I do not visit the eBay website, all web access is denied by Sophos Web Protection. Web access appears to be fine when using Agent/Browser authentication, this issue does not affect devices which use a profile with Agent/Browser authentication set as the default.

I really don't know what is going on here, the issue has been on-going for some time now and it is getting quite annoying now. Has anybody else experienced this strange anomaly? 

Regards,
Richard

  • Hi, Richard, and welcome to the new UTM Community!

    First, we all agree with you about the clunkiness of this place.  Right now, I'm compiling a post that you will find at the top of the General Discussion forum tomorrow.

    I haven't heard of this problem.  What version are you on?  What browser are you using?  Please show us a line from the Web Filtering log where an access was blocked but should have passed.

    Cheers - Bob
