Hi, There are 2 options for you. When you don't have any user you can pass a header X-Auth-Token: $ADMIN_TOKEN where $ADMIN_TOKEN is admin token configured in your keystone.conf. Then you can create any users and set the roles for them using keystone api. It's described here: Manage users: http://docs.openstack.org/api/openstack-identity-service/2.0/content/User_Operations_OS-KSADM.html Manage roles: http://docs.openstack.org/api/openstack-identity-service/2.0/content/Role_Operations_OS-KSADM.html 2013/7/11 Narayanan, Krishnaprasad <narayana at uni-mainz.de> > Hallo all,**** > > ** ** > > Can somebody tell me how to assign an admin role to an user in keystone in > OpenStack ESSEX?**** > > ** ** > > If I have to get the VM details using the nova api, what are the input > credentials that I need to pass for getting the information?**** > > ** ** > > Thanks**** > > Krishnaprasad**** > > _______________________________________________ > Mailing list: https://launchpad.net/~openstack > Post to : openstack at lists.launchpad.net > Unsubscribe : https://launchpad.net/~openstack > More help : https://help.launchpad.net/ListHelp > > -- Cordialement, Semen[Simon] MARCHUK.
