| | Using client-side data signing/encryption and wrapping inter-host
communication into stunnel. |

| | We've yet to get authenticated time, though. | 
| | |  | 
| | |  | 
| | 
| 
| 
| 
| | We can therefore spare some lookups on the MDA, and use static:all
instead. |

| | The clients are identified using their certificate, and connect securely
to the SyncProv.
There are a few workarounds (XXX) in the ACLs due to Postfix not
supporting SASL binds in Wheezy.
Overview:
  - Authentication (XXX: strong authentication) is required prior to any DIT
    operation (see 'olcRequires').
  - We force a Security Strength Factor of 128 or above for all operations (see
    'olcSecurity'), meaning one must use either a local connection (eg,
    ldapi://, possible since we set the 'olcLocalSSF' to 128), or TLS with at
    least 128 bits of security.
  - XXX: Services may not simple bind other than locally on a ldapi:// socket.
    If no remote access is needed, they should use SASL/EXTERNAL on a ldapi://
    socket whenever possible (if the service itself supports SASL binds).
    If remote access is needed, they should use SASL/EXTERNAL on a ldaps://
    socket, and their identity should be derived from the CN of the client
    certificate only (hence services may not simple bind).
  - Admins have restrictions similar to that of the services.
  - User access is only restricted by our global 'olcSecurity' attribute. |

| | For some reason giraff doesn't like IPSec.  App-level TLS sessions are
less efficient, but thanks to ansible it still scales well. | 
| | |  | 
| | 
| 
| 
| 
| | Also, add the 'managesieve' RoundCube plugin to communicate with our
server. | 
| | |  | 
| | 
| 
| 
| 
| 
| | We use a "master" NTP server, which synchronizes against stratum 1
servers (hence is a stratum 2 itself); all other clients synchronize to
this master server through IPSec. |

| 
| | (For now, only LMTP and IMAP processes, without replication.) |
