<div dir="ltr">Hi guys,<div><br></div><div>I only did Keystone, so I am not sure about other services, like nova or else. For Keystone Identity switch, basically, you need to add V3 endpoint and set up some variables. You can check this link: <a href="http://www.cloudkb.net/how-to-change-keystone-api-v2-v3/">http://www.cloudkb.net/how-to-change-keystone-api-v2-v3/</a>. </div><div><br></div><div>We finally found out what I did wrong when I switched from V2 to V3. For icehouse, I used keystone command to created v3 endpoint, it worked well. However, for some reason, it didn't work for Juno. For Juno, you have to use openstack command to create v3 endpoint, and it works perfect. So problem solved. Cheers! </div><div><br></div><div>Thanks for all! :)</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Apr 4, 2015 at 10:41 PM, Adam Young <span dir="ltr"><<a href="mailto:ayoung@redhat.com" target="_blank">ayoung@redhat.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div dir="ltr">Hi guys,

</div>
<div>I have done switching Keystone Identity V2 to V3 in
Icehouse and it works perfect. However, I use the same way to
switch Keystone Identity V2 to V3 in Juno, it doesn't work. It
give me the error: "ERROR: openstack Internal Server Error
(HTTP 500)". </div>
<div><br>
</div>
<div>I traced back to the code, find the error comes from
apache, but it doesn't make any sense that apache has problem,
it might be some problem of keystone which lead to error of
apache. </div>
<div><br>
</div>
<div>Does any one have any idea of it? Thanks!</div>

Bet she's hitting token size issues, as that is an issue in the
header going between mod_ WSGI and HTTPD. Try switching to UUID
tokens.<br>
