Hi,

In multi-region configuration : multi keystone, multi database
but with a common ldap. Is-it possible on Horizon to switch
region without re-authenticate ?

For reason of latency or RTT, it is not possible to share the databases
between the keystone indeed the sites could be geographically distant.

Is there a solution perhaps using :
Kerberos + SSO/ Fernet token/ K2K + SSO ?
