UPGRADING ========= +New GUID Index mode in sam.ldb for the AD DC +-------------------------------------------- + +Users who upgrade a Samba AD DC in-place will experience a short delay +in the first startup of Samba while the sam.ldb is re-indexed. + +Unlike in previous releases a transparent downgrade is not possible. +If you wish to downgrade such a DB to a Samba 4.7 or earlier version, +please run the source4/scripting/bin/sambaundoguididx script first. NEW FEATURES/CHANGES ==================== +New GUID Index mode in sam.ldb for the AD DC +-------------------------------------------- + +The new layout used for sam.ldb is GUID, rather than DN oriented. +This provides Samba's Active Directory Domain Controller with a faster +database, particularly at larger scale. + +The underlying DB is still TDB, simply the choice of key has changed. + +The new mode is not optional, so no configuration is required. Older +Samba versions cannot read the new database (see the upgrade +note above). + KDC GPO application ------------------- -- 2.34.1
