I've seen this question asked here before, although the resolutions have not worked out for me.
I've connected our PRTG installation to Active Directory under Core & Probes settings. All goes through smoothly with the PRTG Service account setting. Although I have also tested "Use explicit credentials" and that works as well.
Now I go into User Groups and configured an "IT Group" which links to an Active Directory Group that is specific to IT users. I made sure to give IT administrative rights. I click on Continue, and the group is set up.
When I try to log into it with my personal IT account which is in the same Active Directory Group that I selected in PRTG, I get this error: "Your login has failed, no corresponding Active Directory Security Group was found. Please contact your administrator!"
What am I doing wrong?
