"SSL Connection failed. Add the following vCenter CA certificate to RPCenter and try again."

Cause

O vCenter Server contém dois certificados diferentes. O primeiro certificado pelos vRPAs que o valida, enviando-o para o servidor do plug-in. Em seguida, o servidor de plug-in tenta entrar em contato com o vCenter para validar se os certificados correspondem. Quando essa chamada é feita, o outro certificado é recuperado, que tem uma assinatura diferente da primeira enviada originalmente para os vRPAs.

Resolution

Solução alternativa:
Adicione os certificados do vCenter ao truststore do servidor do plug-in seguindo este procedimento:
  1. Faça download dos certificados do vCenter Server usando a seguinte URL: 
    http://vCenterIP/certs/download.zip  
Nota: Pode ser necessário tentar vários navegadores para fazer download do arquivo.zip, dependendo de suas configurações de segurança. 
  1. Extraia o arquivo .zip baixado.
  2. Vá para o diretório \certs\lin nesse arquivo e renomeie todos os certificados incluídos adicionando .pem no final do nome do arquivo.
Veja abaixo um exemplo dos certificados listados:
       Exemplo de listagem de certificados
Figura 1: Exemplo de listagem de certificados
  1. Copie todos os certificados no diretório /etc/pki/trust/anchors do servidor do plug-in. Para ter acesso ao servidor do plug-in usando SSH, faça log-in no servidor do plug-in usando o console com credenciais root e desative o firewall usando o seguinte comando:
/sbin/SuSEfirewall2 off 
  1. Execute o seguinte comando no servidor do plug-in para atualizar a lista de certificados confiáveis.
update-ca-certificates 
  1. Execute novamente o assistente configure plug-in a partir do WDM.
  2. Depois de validar se tudo está funcionando bem, habilite o firewall no servidor do plug-in usando o seguinte comando:
/sbin/SuSEfirewall2 on
