[Samba] cant set read-only attr. on office files in 1 share.

[rmi]

Lo folks,

I have samba3 running on my redhat 8 system.
Two shares are available: my "main" share and my "homes" shares.
I cant set read-only attr on office files on my main share. 
But i can set them in my homes share. 

Ive read something about a bug beeing fixed in 3.0.1 but then i shouldnt 
be able to set read-only in my homes share ...or am i mistaking ?

There is however 1 difference between these 2 shares. the "main" share has POSIX ACL's on the files and the "homes" share doesnt have them.
POSIX ACL's are working perfect btw. Any1 got a clue on how to tacle this issue....

Thx in advance
