[2016-05-16 15:22:33,696] ERROR {org.wso2.carbon.identity.oauth2.token.handlers.grant.PasswordGrantHandler} -  **Token request with Password Grant Type for an invalid tenant** : https://server-name:9

To me it looks like you are using a tenant that does not exist. If you don't need tenancy, do not type anything to the tenant domain field. Leave domain field blank when login in so that it uses the super tenant. Only enter the username and the password.
