Comment 1 for bug 1408845

I think we need more info here, like the actual server logs that indicate where the exception is happening. I tried to replicate this with devstack and i couldn't disable the user:

$ keystone user-update testo --enabled false
Unable to update user: You are not authorized to perform the requested action: Disabling an entity where the 'enable' attribute is ignored by configuration. (Disable debug mode to suppress these details.) (HTTP 403) (Request-ID: req-327ab96c-4376-498c-a7a7-47a45cfd9b77)
