The idmap design has also been changed to +centralize control of foreign SID lookups and matching to UNIX +uids and gids. + + +Brief Description of Changes +---------------------------- + +1) The sid_to_uid() family of functions (smbd/uid.c) have been + reverted to the 2.2.x design. This means that when resolving a + SID to a UID or similar mapping: + + a) First consult winbindd + b) perform a local lookup only if winbindd fails to + return a successful answer + + There are some variations to this, but these two rules generally + apply. + +2) All idmap lookups have been moved into winbindd. This means that + a server must run winbindd (and support NSS) in order to achieve + any mappings of SID to dynamically allocated UNIX ids. This was + a conscious design choice. + +3) New functions have been added to winbindd to emulate the 'add user + script' family of smbd functions without requiring that external + scripts be defined. This functionality is controlled by the 'winbind + enable local accounts' smb.conf parameter (enabled by default). + + However, this account management functionality is only supported + in a local tdb (winbindd_idmap.tdb). If these new UNIX accounts + must be shared among multiple Samba servers (such as a PDC and BDCs), + it will be necessary to define your own 'add user script', et. al. + programs that place the accounts/groups in some form of directory + such as NIS or LDAP. This requirement was deemed beyond the scope + of winbind's account management functions. Solutions for + distributing UNIX system information have been deployed and tested + for many years. We saw no need to reinvent the wheel. + +4) A member of a Samba controlled domain running winbindd is now able + to map domain users directly onto existing UNIX accounts while still + automatically creating accounts for trusted users and groups. This + behavior is controlled by the 'winbind trusted domains only' smb.conf + parameter (disabled by default to provide 2.2.x winbind behavior). + +5) Group mapping support is wrapped in the local_XX_to_XX() functions + in smbd/uid.c. The reason that group mappings are not included + in winbindd is because the purpose of Samba's group map is to + match any Windows SID with an existing UNIX group. These UNIX + groups can be created by winbindd (see next section), but the + SID<->gid mapping is retreived by smbd, not winbindd. + + +Examples +-------- + +* security = server running winbindd to allocate accounts on demand + +* Samba PDC running winbindd to handle the automatic creation of UNIX + identities for machine trust accounts + +* Automtically creating UNIX user and groups when migrating a Windows NT + 4.0 PDC to a Samba PDC.
