I'm not sure how long this has been going on but one of my vRealize Operations Managers is no longer syncing with AD and I cannot authenticate with my AD account. I have an Authentication Source setup and it was working however when I tried to sign in today it told me invalid credentials. I had to use my SSO administrator account to finally get in. My auth source is still setup however when I try to test it I get "ERROR_NULL_RESULT_FROM_SERVER". I have another vRrealize Operations Manager for a different cluster and it's working just fine with the same auth source.
This is my version and build.
Version 6.4.0.4635874
Build 4635874
I have tried to delete the auth source and re-create it but that doesn't work. I have also tried pointing it at my other domain controllers but that gives the same error.
Anyone had this issue or know how to fix it?
