[Discovery-R3.1]: Discovery server not accepting admin token in X-Auth-Token header of incoming request

[Pulkit Tandon]

R3.1- Build 14.

Enabled keystone authentication for discovery by editing contrail-disocvery.conf
auth = keystone

Added the credentials in the .conf file:
[KEYSTONE]
auth_host = 77.77.1.10
auth_protocol = http
auth_port = 35357
admin_user = admin
admin_password = contrail123
admin_tenant_name = admin

Send a Publish request to discovery server including X-Auth-Token header.
The request is failing:
Request Fail!! Operation status 500

Pulkit, publish is not subject to authentication via token. LB and admin-state change operation are.
