<div>The keystone client does indeed hide failures from you and wrap them, which makes it annoying to debug, see <a href="https://bugs.launchpad.net/python-keystoneclient/+bug/1210625">https://bugs.launchpad.net/python-keystoneclient/+bug/1210625</a>. If you
do a —debug however you can see the exact call you are attempting and how to repro it with curl. To get a token, you need to POST, I figure the default action for curl is a GET which may be why you are having issues with your curl command. </div>
<div><br>
</div>
<div>Here is a curl request to get a token.</div>
<div><br>
</div>
<div>
<div>keystone --debug token-get</div>
<div>DEBUG:keystoneclient.session:REQ: curl -i -X POST http://example.com:5000/v2.0/tokens -H "Content-Type: application/json" -H "Accept: application/json" -H "User-Agent: python-keystoneclient" -d '{"auth": {"tenantName": "admin", "passwordCredentials": {"username":
"admin", "password": "myPassword"}}}'</div>
</div>

<div><br>
</div>
<div>More debugging hints:</div>
<div><br>
</div>
<div>If you still have problems the server-side logs are generally way more useful. You can enable debug in the config file and then run keystone by hand (after stopping it) by doing /usr/bin/keystone-all. That will generally provide better feedback.</div>
<div><br>
</div>
<div>Also :35357 is the service endpoint for which I usually use a service token, is there a reason you're using that and not the standard :5000?</div>
