Comment 8 for bug 960977

Running `. openrc admin` should have actually been `. openrc admin admin`. The difference is that the first command leaves OS_TENANT_NAME set to 'demo' while the second explicitly sets it to `admin`. This is obviously just user error / doc bug / not very intuitive and lands on devstack.

Second, it looks like OS_TENANT_NAME is not effective (and still produces the "Invalid tenant (HTTP 401)" error. Setting `export OS_TENANT_NAME=` and instead using `export OS_TENANT_ID=<admin tenant ID>` appears to workaround the issue. Need to further investigate this issue in keystone/keystoneclient.
