Did you find a solution for this? I am also getting this alert. I have been to Administration...Access..Authentication Sources, edited the Authentication Source for Active Directory, clicked the Test button and it failed. I did not have Use SSL/TLS selected so I have now selected this and when I Test it it displays details about the certificate on the Domain Controller, asks me to Accept it and then confirms that the "Test connection was successful". But I still get this alert every 30 minutes.
Do I need to add the certificate from the domain controller or the signing CA's certificate to a trust store on the vRealize Operations appliance somewhere?
