When a Windows principal that is not mapped to a specific database user accesses a database by using membership in a windows group or AAD group, a user id of 0 may be assigned to the user. When the user tries to use libraries that are installed by other dbo/sysadmin user, the user may not see any external libraries. After applying this update, a user id of 0 would have access to external libraries installed by the dbo (libraries in public scope). Since there is no database user that is mapped to the Windows principal, the user with user id 0 cannot create or install external libraries. | SQL Engine | Windows | ||
