[Samba] Strange permissions problems

I had this problem some last year and never got it figured out. Now it
is bugging me. It seems that sometimes when a student writes his/her
file to a directory, it will not keep the correct group. It puts
his/her main group as the group owner and that fouls things up. Here is
what I have.
/school 3777 admin.teacher
/school/bhs 3777 admin.teacher
/school/bhs/reese 3777 reese.teacher
/school/bhs/reese/6thhour 3777 reese.teacher
Now rosie creates her first directory in ....6thhour
/school/bhs/reese/6thhour/rosie 3770 rosie.teacher
/school/bhs/reese/6thhour/rosie/word 3770 rosie.teacher
/school/bhs/reese/6thhour/rosie/word/chap1 3770 rosie.teacher
Samba share that rosie gets:
path = /school/bhs
read only = no
valid users = @teacher @admin @bhs
create mask = 660
force create mode = 2660
directory mask = 770
force directory mode = 3770
So here is how it goes. Rosie can make directories-files below
.../6thhour (she is in the bhs group). Everything seems fine and dandy.
All folders-files are getting permissions that they should so that
rosie and the teacher (all teachers are in the teacher group) are the
only ones able to see anything in the folder that she created
(.../rosie). Then when she gets down to the chap1 directory and puts a
file in it, the file has the user and group rosie.bhs (bhs is her main
Now suddenly the teacher cannot access the files since she is not in the
bhs group. Any idea why this is not pulling down the teacher group with
the files since I have the bit set to keep the group of the directory?
It pulled it down in the directories above (all files above had the user
group rosie.teacher), but it seems that it quit when it go this deep in
One other thing that is strange, is that some of them do have the user
group correct. There are 2 files in the .../chap1 directory that have
the user and group rosie.teacher just like they should.
I logged on with her username just to test this and the files that I
saved had the user and group rosie.bhs.
Thanks for any help.
