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.
