the RSA_USER and RSA_DBA has appropriate access. as currently we restored the services back to the old vCenter server and its all working normal. so I think its not a permission issue. I observed some error in
imstrace log
ERROR, ServerName,,,,LDAP Server connection test failed javax.naming.AuthenticationException: GSSAPI [Root exception is javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Server not found in Kerberos database (7))]]
