AD SSO suddenly stopped working

Hello, guys! I will try to be short.

The power went out for a long period a couple days ago and that caused UTM to restart. Because of that web surfing through AD SSO suddenly stopped working. To be more specific, I have no idea why their credentials isnt being used and because of that users are getting blocked pages (obviously).

2023:01:04-03:08:46 asg220akrk httpproxy[13050]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="CONNECT" srcip="172.16.2.156" dstip="" user="" group="" ad_domain="" statuscode="403" cached="0" profile="REF_DefaultHTTPProfile (Default Web Filter Profile)" filteraction="REF_HttCffFilteActioCall (Filter Action Call Center)" size="3212" request="0x33e8c00" url="">consulta4.confirmeonline.com.br/" referer="" error="" authtime="2" dnstime="0" aptptime="0" cattime="0" avscantime="0" fullreqtime="206860" device="1" auth="2" ua="" exceptions=""



I´ve done a few things like: rejoining again, restarting proxy and even restarting UTM (I know, eek!). 
I am not going to say about checking DNS forwarders, time sync between AD and Sophos, if FQDN (both ways) can be resolved and stuff like that because I consider this "home work" and I have already checked them. After all, everything was working smoothly.

It´s been a looong time I dont put in the work because I had a tech for that but he left a few days ago. So yeah, I have to get things done.
By the way, I read some issues in the current firmware (9.713-19) which is the one I am using but my problem doesnt seem one of them.

Appreciate any help!

  • Hello, Vivek! Thanks for the reply.

    I am aware of those links you posted. I read them again just to be sure that I was not missing anything, but no success. As I said, everything was working fine so I dont believe those configurations messed up by themselves (is that even possible?).

    I dont know if that helps, but some of those users use firefox for some websurfing and it worked fine too. It is still prompting for credentials, but it doesnt matter if they input. It doesnt work:

    2023:01:04-02:20:01 asg220akrk httpproxy[13050]: id="0001" severity="info" sys="SecureWeb" sub="http" name="http access" action="pass" method="GET" srcip="172.16.2.156" dstip="" user="weverton.alves" group="" ad_domain="AKRKPROMOTORA" statuscode="307" cached="0" profile="REF_DefaultHTTPProfile (Default Web Filter Profile)" filteraction=" ()" size="0" request="0x281e000" url="">asg220akrk/auth referer="" error="" authtime="2342" dnstime="0" aptptime="0" cattime="0" avscantime="0" fullreqtime="225070" device="1" auth="2" ua="Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:102.0) Gecko/20100101 Firefox/102.0" exceptions=""

    After that line, there is a lot of attemps in the log with this:

    2023:01:04-02:20:01 asg220akrk httpproxy[13050]: id="0002" severity="info" sys="SecureWeb" sub="http" name="web request blocked" action="block" method="GET" srcip="172.16.2.156" dstip="" user="" group="" ad_domain="" statuscode="403" cached="0" profile="REF_DefaultHTTPProfile (Default Web Filter Profile)" filteraction="REF_HttCffFilteActioCall (Filter Action Call Center)" size="3216" request="0x2bb0b00" url="">detectportal.firefox.com/canonical.html" referer="" error="" authtime="2" dnstime="0" aptptime="0" cattime="0" avscantime="0" fullreqtime="379" device="1" auth="2" ua="Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:102.0) Gecko/20100101 Firefox/102.0" exceptions=""

  • Are there any updates arround this thread? Because my SSO isn't working any longer too. I could not find any error. Auth is working fine, the sg could prefetch users and groups, server and user test is ok but SSO has emtpy user and group information Disappointed

    also re-joined the ad without any problems - until last week some user from a co-loc with different IP-Range were logged but today they are empty too - any ideas ?
