Please find the Red Hat Satellite 6 product page here with release notes and more relevant informations.
This article describes very well above mentioned topic. Afterwards you should be able to manage sudo rules centrally in LDAP or Active Directory and access them through sssd for example. Have fun while reading.
If you configure multiple network cards in your RHEL machine with more than one gateway then you can use “policy based routing” to configure the network traffic in a way where the traffic will leave the same interface where the traffic came from.
This procedure is described in this Red Hat KCS article.
I also created a Puppet module to configure policy based routing on RHEL 6 / 7. Currently this module does not handle Bond or VLAN tagged interfaces. You can find my module here.
Puppet Lint is a nice tool to check the syntax of your Puppet code. Common errors can be fixed directly with Puppet Lint. It can also be included to CI tools like Jenkins if you want to check your Puppet code during a Jenkins build job for example.
Find out more about Puppet Lint here.
If you are creating a custom fact and want to test the output of your fact then you need to perform the following command:
$ FACTERLIB=/path/to/your/fact/ facter
Satellite 6 offers the possibility to provision a host with multiple network cards, however an issue is faced when using VMWare in conjuction with Satellite 6 and you want to provision multiple network interfaces with static IP addresses.
What happens is that after the provisioning of a virtual machine is complete, multiple network cards are added, but only the primary interface (which is used for PXE / DHCP during installation) is configured correctly.
I created a workaround to get this working. I described this solution in an official Red Hat KCS article which is now verified by Red Hat Engineering and published to the public. You can find this article here.

If you plan to deploy RHEL guests with Satellite 6 and your DNS server of choice is Microsoft DNS than Satellite 6 is also able to create / delete appropriate DNS entries for newly created hosts automatically via foremen-proxy on Microsoft DNS. This article describes on how to configure both Satellite 6 and Microsoft DNS.
You will find a good overview of common administrative commands in RHEL 5, 6 and 7 on the following link.
