[Samba] concurrent ms access usage does not work with 3.4.3

[Andreas Moroder]

Since we upgraded samba to 3.4.3 ( from 3.0.26a ) on our fileserver only 
one user at a time can use a ms access ( .mdb ) program we wrote. The 
second user that tries to start this application gets a message that the 
mdb is lockeb by another user. The strange thing is that I as 
administrator can connect as second uset to the mdb without problems.

Is this a known probleme and is there a solution ?

Thanks
Andreas
