In another thread that has not yet been restored at astaro.org:
"I have found a few posts similar with this error message but non of them seem to help.
I installed the Sophos Agent on my local machine (Win 8) and entered my Active Directory credentials, this worked a treat and web filtering was working as expected.
I then restarted the machine and logged back on with the same credentials and I get the error:
Could not validate certificate! SAA will now close
Tried uninstalling / reinstalling etc but the error remains.
Any help please."
I have the same problem. I noticed when I installed SAA on other computers, it included a certificate import that is NOT happening on this laptop (SAA works on all the other computers I've tried thus far). I removed all the various certificates that have been downloaded from the UTM since I first installed and tried a reinstall of SAA, but that still didn't do the certificate install phase. I have tried manually installing various CA certificates from the UTM, but I still apparently haven't found the right one.
What do I need to do to get the right certificate on this laptop?
