OAuthException access_denied: Cannot authenticate user 'openbacchus@internal'

[virtio-technique]

I have tried to use user openbacchus@internal in ovirt-engine to login from openbacchus web console. But auth failed with error in ovirt engine log:

2018-08-15 10:06:39,681+03 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-25) [] EVENT_ID: USER_VDC_LOGIN_FAILED(114), User openbacchus@internal connecting from '10.169.2.2' failed to log in : 'Unable to log in. Verify your login information or contact the system administrator.'.

But if use curl to examine ovirt API auth going with no problems:

curl -u openbacchus@internal:XXX https://ovirt.XXX/ovirt-engine/api --insecure

you need to use admin@internal account to use it.
