Hi metze,
I reject it when the lanman auth is deactivated. But otherwise it should
be enabled (think at "dcesrv_samr_ChangeOemPassword2" which manipulates
only the lanman hash - tested using the passwords torture test).
Therefore it should also be valid to have only a "dBCSPwd" attribute in
the DB (I read also the MS-SAMR documentation and this seems possible).
But this patch prevents a change which would delete all password
attributes - which is fatal.
This work is still not complete since there are some outstanding
differences in beaviour s4 <-> torture SAMR passwords.
