Recently a friend pointed me in the direction of a rather useful piece of software for doing quite funky things with backing up and restoring PostgreSQL databases.
Most organizations I have seen using PostgreSQL and MySQL have always chosen to perform database backups locally on each server. This is fine and it works, but you need to ensure you take a backup of those backup files. I’ve not come across any piece of software that will do complete database backups remotely… that is, until now. This is where “barman” fits in. You can check out what they are all about on the project’s website. http://www.pgbarman.org/
In this article I’ll be going through a really quick howto on getting up and running with Barman in order to perform remote backups of postgresql servers.
In this example I will be using the below details. Read more
I have also posted this article on the FreeIPA.org project wiki which is linked here
The below details will walk you through how to add a Red Hat Enterprise Linux 6.2 system to an IPA domain, and then configure Dovecot to allow single sign on to user mailboxes with IMAP/S.
Details of this example are as follows
Domain name: example.com IPA Server: ds01.example.com Dovecot Server: mail01.example.com IPA Client: workstation01.example.com IPA User: user1 and user2
Please Note: This guide describes using SSL combined with Dovecot to deliver IMAPS support. This guide is not designed to cover how to create a valid SSL vertificate. This guide uses the default dovecot generated certificate and it is HIGHLY recommended that if you wish to deploy this into a production environment, that you replace this certificate with your own trusted/validated certificate Read more

Here we will be walking through configuring postfix for the following criteria:
Please be aware that this article does not cover accessing a user’s mailbox as this is covered in the following article.
Before I continue I’d like to thank Loris Santamaria and Anthony Messina from the freeipa-users@redhat.com mailing list for their assistance in getting this solution working.
