URGENT: WinPOPUp triggers permission problem

[Mircea Ciocan]

        Dear SAMBA gurus,

        I browsed the list archives but found nothing relevant about
this big
(IMHO) problem. Only just another problem like mine, unfortunately
unanswerd :(.
        I have here samba-2.0.3 on a Linux box, libc5, manually compiled
without problems. BTW kernel is 2.2.7ac1.
        All is well EXCEPT WinPopUp messages, I can send them OK but I
cannot
receive.
        As receiver I set LinPopUp but I don't think that is ever called
because the message get lost and on every message that I receive I get a
entry in the <machine name>.log that looks like:
mircea:/usr/local/samba/var# cat log.mircea
[1999/05/02 18:27:04, 0] locking/shmem.c:smb_shm_unregister_process(435)
  ERROR smb_shm_unregister_process : processreg_file open failed with
code Permi
ssion denied /usr/local/samba/var/locks/SHARE_MEM_FILE.processes
                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        This is my contribution, I added in the debuging section of
shmem.c the
printing information for file name.
        On my system this file is created automatically when first
message
arrive and its permissions are 644 root:root.
	So, supposing that is some kind of permissions problem I changend the
guest user from nobody -> guest -> <user with a valid shell/group> ->
root.
	When the guest user reached root all started  to work well, but of
course this is a horrible security nightmare and I'm shure that is a
better and secure approach.
        If some of you can shed some light on that problem I'll be very
greatefull because I'm allmost finihed my hair-to-tear supply.

                Yours,

                Mircea C.
