We have a PRTG installation that is integrated with our Active Directory. Most users can log in successfully but 2 accounts that were working, where locked out on AD. The 1 is now working fine after the hour poll but the other one is not working. I have cleared the cache which has not fixed the issue. We are using an explicit account to for the AD integration that as all the correct rights, seeing the other uses can log in successfully. Do you have any other suggestions? We are using PRTG Network Monitor 188.8.131.522+.
