Comment 4 for bug 1578137

Steps to reproduce:
1)Create cluster. in #cluster/1/settings/general OpenStack Access are:
Username: rados
password: rados
2) Deploy cluster
3) Change password in horizon to "admin"
fuel --env 1 health --check smoke
[ 1 of 11] [failure] 'Create instance flavor' (0.2007 s) Authorization failure. Please provide the valid credentials for your OpenStack environment, and reattempt.
[ 2 of 11] [failure] 'Check create, update and delete image actions using Glance v2' (0.009402 s) Authorization failure. Please provide the valid credentials for your OpenStack environment, and reattempt.
###
fuel --os-username=rados --os-password=admin --env 1 health --check smoke
Unauthorized: need authentication!
Please provide user and password via client
fuel --os-username=user --os-password=pass [action]
or modify your credentials in your configuration file.
####
So, issue about openstack env credentials, not fuel itself.
