Description

These pages describes just how to setup and configure cross-forest trust between an IPA domain and an advertisement (Active Directory) domain.

Prerequisites

  • FreeIPA 3.3.3 or later is preferred
  • Windows Server 2008 R2 or later on with configured AD DC and DNS installed locally in the DC

You can follow article Setting up Active Directory domain for evaluation purposes if you wish to install and configure AD DC for testing purposes.

IPv6 stack use

Suggested means for modern networking applications would be to just available IPv6 sockets for paying attention because IPv4 and IPv6 share the port that is same locally. FreeIPA utilizes Samba included in its Active Directory integration and Samba requires enabled IPv6 stack in the device.

Adding ipv6. Disable=1 towards the kernel command line disables the entire IPv6 stack

Adding ipv6. Disable_ipv6=1 will keep the IPv6 stack functional but will maybe not designate IPv6 details to your of one’s system products. This is certainly suggested approach for instances once you do not utilize IPv6 networking.

Creating and contributing to as an example /etc/sysctl. D/ipv6. Conf will avoid assigning IPv6 details to a certain system screen

Where interface0 is the specific user interface.

Remember that all we have been requiring is IPv6 stack is enabled in the kernel degree and also this is preferred option to develop networking applications for the very long time currently.

Trusts and Windows Server 2003 R2

As noted above, the necessity for trusts is Windows Server 2008 R2. While cross-forest trusts were put into woodland practical degree Windows Server 2003, you can find extra requirements imposed by utilization of AES encryption kinds which need domain functional degree Windows Server 2008. You are able to begin a trust between a FreeIPA server and Windows Server 2003 R2, with limited functionality with just RC4 and DES encryption kinds. Next paragraph defines the actions required to carry out this. Take note, nevertheless, that this is certainly unsupported, extremely experimental and of really value that is limited of this poor encryption types for trusted domain objects which may be reasonably simple cracked with present improvements in technology.

So that you can establish a trust between a FreeIPA host and a Windows Server 2003 R2, you’ll want to improve the forest functional degree to Windows Server 2003. To work on this, available ‘Active Directory Domains and Trusts’ snap-in and right-click on ‘Active Directory Domains and Trusts’ root into the left pane. Then select ‘Raise forest functional degree. ‘ and employ ‘Windows Server 2003’ once the known degree to boost.

Make certain you perform this course of action before developing a trust because of the ‘ipa trust-add’ command. The remainder setup is just like compared to Windows Server 2008 R2.
