if i create a Vsphere Cloud and one template => check template is working fine. If i then duplicate the template entry and try "check template" on the second, i get the following error message

Problem validating org.jenkinsci.plugins.vsphere.tools.VSphereException: com.vmware.vim25.InvalidLogin: The logon can not be completed due to an incorrect user name or password

If i create another Vsphere Cloud and one template their, it is also working, only the second template is not working.
