puppet can not start keystone with message:
http://paste.openstack.org/show/100500/
After environment reverting I run keystone manually without problems:
[root@node-1 ~]# /sbin/service openstack-keystone status
keystone is stopped
[root@node-1 ~]# /sbin/service openstack-keystone start
Starting keystone: [ OK ]
[root@node-1 ~]# /sbin/service openstack-keystone status
keystone (pid 23019) is running...
