multi-master with mysql backend

I could succesfully setup bind with mysql backend and it works using 
bind-mysql driver.

everything works except that nsupdate will no longer work.

is this normal ??

requests sent for adding a RR using nsupdate are ignored by named when 
using mysqldb backend
while they are honoured and served when using normal file backend.

is this a normal behaviour ?

how to use nsupdate even if with a different backend which is not the 
default  file backend ?

any hints ?

thank you
