Yes, i know this breaks the compatibility with all existing tdbsam bases.
We try to find out the correct place for theses informations but it's 
not easy.
We think that the unknown5 field contains theses informations, according 
to ethereal. But it's difficult to work with this field due to all of 
its occurences in samba code. No documentations are available for it.
Could we have more details about this field and the structures ?

But for the other backends ?
Moreover, this will force users to use the newest versions of LDAP ?
Obviously it's a problem, but the possibilities that a user try to log 
on many times on at the same moment is rare :).

The patch corrects too a small mistakes in pdb_xml.c
-> s/login/logon/
