Description of problem:
current version of oc shows an error:
$ oc-3.7.9 whoami
Error from server (Forbidden): User "developer" cannot get user.openshift.io.users at the cluster scope

Version-Release number of selected component (if applicable):
Markuss-MacBook-Pro:ansible mschreie$ oc-3.7.9 version
oc v3.7.9
kubernetes v1.7.6+a08f5eeb62
features: Basic-Auth

Server https://openshift.hailstorm2.coe.muc.redhat.com:443
openshift v3.5.5.31
kubernetes v1.5.2+43a9be4


How reproducible:
oc login
user: admin
oc whoami
-> error

Doing the same with older version of oc works, e.g.:
oc version
oc v3.6.173.0.83
kubernetes v1.6.1+5115d708d7
features: Basic-Auth

Server https://openshift.hailstorm2.coe.muc.redhat.com:443
openshift v3.5.5.31
kubernetes v1.5.2+43a9be4



Actual results:
Error from server (Forbidden): User "developer" cannot get user.openshift.io.users at the cluster scope


Expected results:
admin

Additional info:
colleague is having same issue on RHEL as I have on MAC when connecting against the same OpenShift installation.
