We have three clusters of ESXi 4.1 host servers in our environment. Each host is configured the same, and each host is a part of the same vSphere Management Assistant. I have noticed recently that on one of the clusters, all of the hosts continue to show the same login errors regarding the vMA. The error messages simply show "Cannot login root@[ip of vma]".
I'm pretty confident that this is occurring because we have lockdown mode enabled. When I log into the vMA and connect to the host (that is locked down), it asks for a username. When I input the correct root credentials, I get "Error: Permission to perform this operation was denied". And with a host that does NOT have lockdown mode enabled, I can connect successfully.
Is there any reason why I continuously see these login errors for my hosts? I mean literally multiple times a day. It's filling up my logs pretty quickly, and I just want to know why. Any help is appreciated, thank you.
