Najdorf + Kasparov-2 Provider VMware warns

[szajac01]

Hi, after kasparov-1 to 2 upgrade, we have a lot of Warns like that
WARN -- : MIQ(ManageIQ::Providers::Vmware::InfraManager::HostEsx#authentication_check_no_validation) type: [nil] for [77] [myEsx.xxx] Validation failed: incomplete, Missing credentials

I tried to revalidate credentials on the Vmware provider, this does not change anything.
I did delete and recreate the provider, no change regarding these warns.

Any ideas ?
What is the potential impact on the application ?

Same events in Najdorf also in another environment, after adding a new VMware provider.
What is the potential impact ?
