For Samba 4.10, the behaviour of the paged results control (1.2.840.113518.104.22.1689, RFC2696) has been changed to more closely match Windows servers, to improve memory usage. Paged results may be used internally (or is requested by the user) by LDAP libraries or tools that deal with large result sizes, for example, when listing all the objects in the database.
Previously, results were returned as a snapshot of the database but now, some changes made to the set of results while paging may be reflected in the responses. If strict inter-record consistency is required in answers (which is not possible on Windows with large result sets), consider avoiding the paged results control or alternatively, it might be possible to enforce restrictions using the LDAP filter expression.
RFC2696 does not specify how an implementation should behave in the case of simultaneous modification.
