* slapd monitoring.Guilhem Moulin2015-06-101
| | | | | We don't use the provided 'slapd_' Munin plugin because it doesn't support SASL binds.
* Configure munin nodes & master.Guilhem Moulin2015-06-104
| | | | | Interhost communications are protected by stunnel4. The graphs are only visible on the master itself, and content is generated by Fast CGI.

* Configure SyncRepl (OpenLDAP replication) and related ACLs.Guilhem Moulin2015-06-071
| | | | | | | | | | | | | | | | | | | | | | | 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.

* Whitelist our IPs against fail2ban.Guilhem Moulin2015-06-071
| | | | | | | This is important as we don't want the IMAP server baning the webmail, for instance. (The fail2ban instance running next to the webmail should ban the attacker, but that running next to the IMAP server shouldn't ban legit users.)
* Replace IPSec tunnels by app-level ephemeral TLS sessions.Guilhem Moulin2015-06-073
| | | | | For some reason giraff doesn't like IPSec. App-level TLS sessions are less efficient, but thanks to ansible it still scales well.

* Don't use generic maps.Guilhem Moulin2015-06-071
| | | | | | | | | | | | | | | | | In fact we want to only rewrite the envelope sender: :/etc/postfix/main.cf # Overwrite local FQDN envelope sender addresses sender_canonical_classes = envelope_sender propagate_unmatched_extensions = sender_canonical_maps = cdb:$config_directory/sender_canonical :/etc/postfix/sender_canonical @elefant.fripost.org admin@fripost.org However, when canonical(5) processes a mail sent vias sendmail(1), it rewrites the envelope sender which seems to *later* be use as From: header.

* Don't require a PKI for IPSec.Guilhem Moulin2015-06-071
| | | | | | | | | | | Instead, generate a server certificate for each host (on the machine itself). Then fetch all these certs locally, and copy them over to each IPSec peer. That requires more certs to be stored on each machines (n vs 2), but it can be done automatically, and is easier to deploy. Note: When adding a new machine to the inventory, one needs to run the playbook on that machine (to generate the cert and fetch it locally) first, then on all other machines.
* Support non-free firmwares. (Can be required :-()Guilhem Moulin2015-06-072
| | | | Also, always install contrib's intel-microcode on Intel CPUs.
* Assume a DNS entry for each role.Guilhem Moulin2015-06-072
| | | | | | E.g., ldap.fripost.org, ntp.fripost.org, etc. (Ideally the DNS zone would be provisioned by ansible, too.) It's a bit unclear how to index the subdomains (mx{1,2,3}, etc), though.
