  I have a mailbox which I want to allow some users (different groups)
  to read from and write to. When I try and use an ACL to control access
  the users with READ+WRITE access still get protection failures when
  trying to access the device.

  Could some kind soul let me know what the problem is ?

  Thanks.

Many thanks to all those who replied to my question on
mailboxes/acls...but the problem still remains unsolved.
I was asked for more detail , so...

1) use $CREMBX to create a mailbox with W:RWLP "protection"
   anyone can read or write to it.

2) put an ACL on the device :
        (id=mbx_holder,access=read+write)
        (id=*, access=none)

3) get a mbx_holder to read/write to the mailbox --> protection error

4) if I give CONTROL access as well the id holder can change the ACL
   as expected but still can't read or write to the device.


I'm puzzling over whether using the ACL is preventing the holder
logical IO access to the device ??

Thanks for your time.
