    s4:drepl_notify: hide some bugs from the make test output
    
    It's useless to get messages like this every few seconds:
    
    dreplsrv_notify: Failed to send DsReplicaSync to
    edbf4745-2966-49a7-8653-99200f1c9430._msdcs.samba2003.example.com for
    CN=Configuration,DC=samba2003,DC=example,DC=com -
    NT_STATUS_OBJECT_NAME_NOT_FOUND : WERR_BADFILE
    
    We have a non bug regarding non-linked DN attributes
    and changes of the target DN.

    s4:drsuapi: don't return all linked attributes at the same time
    
    Windows gives them in chunks, but I don't know the correct
    rule to calculate the chunk size.
    
    For now I'll use 1500 as the max size.
    
    Windows isn't happy when it gets ~ 100000 linked attributes in one
    response. It corrupts its directory index and later moves some objects
    to the LostAndFound folder.
