Just confirming... By removing the "driver = memcached" line out from<br>
[token] section in keystone.conf, it seems to be working:<br>
<br>
---<br>
user@liberty-1:~$ openstack --os-auth-url<br>

Do you thinks that it is "safe" to continue? I'm wondering about side<br>
effects of this (no memcached anymore?)...<br>
