(Adding another member of our team Douglas)

Hello Giuseppe,

For questions about news or patches for Keystone's PKI vs UUID modes, you might 
reach out to the openstack-...@lists.openstack.org mailing list, with the 
subject line prefixed with [openstack-dev] [keystone]

Our observation has been that the PKI mode can generate large text blocks for 
tokens (esp. for large service catalogs) that cause http header errors.

Regarding the specific barbican scripts you are running, we haven't run those 
in a while, so I'll investigate as we might need to update them. Please email 
back your /etc/barbican/barbican-api-paste.ini paste config file when you have 
a chance as well.

Thanks,
John

Subject: [Openstack] [Barbican] Keystone PKI token too much long

Dear all,
I have configured Keystone for Barbican using this 
guide<https://github.com/cloudkeep/barbican/wiki/Developer-Guide-for-Keystone>.

Is there any news or patch about the need to use a shorter token? I would not 
use a modified token.

Following you can find an extract of the linked guide:

  *   (Optional) Typical keystone setup creates PKI tokens that are long, do 
not fit easily into curl requests without splitting into components. For 
testing purposes suggest updating the keystone database with a shorter 
token-id. (An alternative is to set up keystone to generate uuid tokens.) From 
the above output grad the token expiry value, referred to as "x-y-z"

mysql -u root
use keystone;
update token set id="foo" where expires="x-y-z" ;

Thank you,
Giuseppe
