Open Stack

Hello,

I would like to use a mysql DB, from its own host, and have all 
openstack daemons talk to it.  So I set up one mysql DB, dump and reload 
the current running DB to it,  changed the sql "connection" setting in 
the keystone config file to point to the new ip, restart keystone 
service, but it doesn't seem to work. The commands like "keystone 
user-list" hang and eventually times out.

Do I miss something here?

Thanks,
Xin
