to allow the FreeIPA KDC to translate the MS-PAC that is sent from a Windows client when requesting a ticket in the FreeIPA realm, and substitute/accompany the original MS-PAC

with a PAD that provides users/groups and login information in a format readily. Remapping to a local or domain account is required unix/Linux Workstation MIT KDC 10 11 Closer Look at Microsoft Approach 12 PAC Privilege Access Certificate Problems: Local users: remapping is not simple and not efficient Domain users: lookups required for every operation AD best Kerberos extension. The inverse can also be done when a FreeIPA user wants to access resources in an AD domain. A Resource Domain is a domain that is explicitly separate from the Domain where regular users are registered. It is clear that interoperability between FreeIPA and AD is therefore a necessity. PAC solves both problems and helps with the trust use case. Where X is: User Desktop Windows vs Non Windows Service Windows vs Non Windows Actions: Note: Different services/resources have different characteristics Login. In order to generate a valid MS-PAC we need to map posix UIDs/GIDs to Windows SIDs, by assigning a Domain SID to our Realm and add some other login related information into the mix. This operation can be done at the KDC level by providing a modified KDB plugin that is able to retrieve user data from the identity store (our ldap server). 21 Resource Domains Use case One concept often used in the Microsoft World is that of Resource Domains. It basically makes the MIT realm a shadow copy of the AD realm. 19 20 More Use Cases to Worry. 14 Relations Between Two Windows Domains And who are you to ask? It goes beyond pure authentication and deeply involved in serving identity information used for access control. 22 23 The Beginning. 25 26 PAD Principal Authorization Data 26 What if we had a way to share authorization information? So these two domains have very different characteristics, use different technologies and have different security requirements. Service in Trusted Service Domain Service in Trusting Service Domain Tell me more about the user, please. 24 25 FreeIPA and AD While FreeIPA is focused on managing Linux/unix servers it is also clear that in many enterprises, actual desktops are Windows machines managed through AD domains. But, if you have 2 different user bases one using Windows AD and the other based on a different directory and using MIT Kerberos for authentication, mapping is less then ideal. The reason is that there is no standard identity store that defines attributes needed by the OS in MIT Kerberos, therefore when using it in conjunction with Windows machines a mapping between local or domain accounts and MIT Kerberos principal names is necessary.

It makes the solution more complex replication delays and fragile. Because servers may be more exposed. There is always something going wrong with. The PAD includes information similar to what is included in the mspac. Oneway can be seen as an appropriate measure to mitigate security breaches consequences 1027 internal only presenter name 2 What is our focus.

This means that querying back for user information is either not possible the trusted realm does not release this information anonymously or trusting client has no network access to trusted realm Domain Controller or it is risky anonymous connections. Convince AD clients our users are legit In order to login into an AD managed client or server with a FreeIPA user we have to provide a mspac to such client in the TGT 28 29 Illustration of Goals Windows Service unixLinux Service Active Directory. At the same time we want to be able to make it easy for FreeIPA admins to manage Windows users access to Linuxunix Servers authorization. MIT Kerberos and AD Dmitri Pal.

Even before Kerberos was introduced with Windows 2000 Servers. At most anonymous connections can be established. AD trusts go beyond the does mac os x come with java classic exchange of passwords for the crossrealm trusts accounts 24 FreeIPA as a Way to Manage unixLinux Machines Red Hat has been sponsoring the FreeIPA project as a way to make it easy to manage group of LinuxUnix machines. But more importantly they have different requirements and skills and deal with different environments. The aim is to build a system that can be easily used by Linuxunix admins and has builtin facilities to address natively the needs of Linuxunix administration. But involve also setting up routing information 12 13 PAC and Trust Relationships 13 Microsoft Windows Domains have always supported the concept of oneway trust relationship. To transparently access a FreeIPA managed Linuxunix server without requiring free app to download music for iphone 6 the user to go thorough secondary authentication SSO 21 22 Production Servers as a Separate Trusted Realm Generally the Windows desktop admins and the Linux server admins are separate divisions within the organization.

Groups are shared so authorizations decisions become common issues, not per realm properties as you would want/expect.Resource and Trusted domains are still used where organizations have clearly separate domain of administration.27 28 Goals in Priority Order AD users accessing services in the FreeIPA domain AD users logging into a unix box and accessing services in the FreeIPA or AD domains FreeIPA users logging into a Windows desktop FreeIPA users accessing Windows services We will deal.Without requiring kerberos clients to perform complex mappings on their own or contact foreign domains servers.
