With system-wide crypto policy in use, arcfour-hmac encryption type might be removed from the list of permitted encryption types in the MIT Kerberos library. Applications aren't prevented to use the arcfour-hmac enctype if they operate on it directly. Since FreeIPA supported and default encryption types stored in LDAP, on the server side we don't directly use a set of permitted encryption types provided by the MIT Kerberos library. However, this set will be trimmed to disallow arcfour-hmac and other weaker types by default. While the arcfour-hmac key can be generated and retrieved, MIT Kerberos library will still not allow its use in Kerberos protocol if it is not on the list of permitted encryption types. We only need this workaround to allow setting up arcfour-hmac key for SMB services where arcfour-hmac key is used to validate communication between a domain member and its domain controller. Without this fix it will not be possible to request setting up a machine account credential from the domain member side. The latter is needed for Samba running on IPA client. Thus, extend filtering facilities in ipa-pwd-extop plugin to explicitly allow arcfour-hmac encryption type for SMB services (Kerberos principal name starts with cifs/).

FreeIPA Server
FreeIPA allows Linux administrators to centrally manage identity, authentication and access control aspects of Linux and UNIX systems by providing simple to install and use command line and web based management tools.
FreeIPA is built on top of well known Open Source components and standard protocols with a very strong focus on ease of management and automation of installation and configuration tasks.
FreeIPA can seamlessly integrate into an Active Directory environment via cross-realm Kerberos trust or user synchronization.
Benefits
FreeIPA:
- Allows all your users to access all the machines with the same credentials and security settings
- Allows users to access personal files transparently from any machine in an authenticated and secure way
- Uses an advanced grouping mechanism to restrict network access to services and files only to specific users
- Allows central management of security mechanisms like passwords, SSH Public Keys, SUDO rules, Keytabs, Access Control Rules
- Enables delegation of selected administrative tasks to other power users
- Integrates into Active Directory environments
Components
The FreeIPA project provides unified installation and management tools for the following components:
- LDAP Server - based on the 389 project
- KDC - based on MIT Kerberos implementation
- PKI based on Dogtag project
- Samba libraries for Active Directory integration
- DNS Server based on BIND and the Bind-DynDB-LDAP plugin
