It is a nationwide healt organization. about 5000 computers, 28000
employees and every facility addresses equivalent issues. File sharing
should be considereded inside each facility, but same LDAP is used for
other application authentication.

MPLS 4Mpbs connections... not fast enough

The idea is to replicate "only" the required information to each facility.
This would give each deploy resilience in case of communication failures
and in case of security compromise (stealth or takeover) of a server,
only local credentials are exposed, not companywide.
