Add endpoint keystone token error

[Denny275]

Hi all,

I met a problem when Adding Openstack endpoint (Infrastructure)

The ZenPacks I installed is ZenPacs.zenoss.OpenStackInfrastructure-2.4.2, Zenoss.core is 6.2.1, Zenoss Control Center is 1.6.2

The error message show "KeystoneERROR unauthorizedERROR: 401 Unauthorized (check username and password)"

I'm sure that username and password are correct,
because I write a python script, try to get keystone token, and the python script run success.
