ipasam already implemented retrieval of groups for MS-SAMR calls. However, it did not have implementation of a group retrieval for the path of lookup_name() function in Samba. The lookup_name() is used in many places in smbd and winbindd. With this change it will be possible to resolve IPA groups in Windows UI (Security tab) and console (net localgroup ...). When Global Catalog service is enabled, it will be possible to search for those groups as well. In Active Directory, security groups can be domain, domain local, local and so on. In IPA, only domain groups exposed through ipasam because SID generation plugin only supports adding SIDs to POSIX groups and users. Thus, non-POSIX groups are not going to have SIDs associated and will not be visible in both UNIX and Windows environments. Group retrieval in Samba is implemented as a mapping between NT and POSIX groups. IPA doesn't have explicit mapping tables. Instead, any POSIX group in IPA that has a SID associated with it is considered a domain group for Samba. Finally, additional ACI is required to ensure attributes looked up by ipasam are always readable by the trust agents.

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
