PROBLEM:
user1 and user2 in group1.
client logged into server through samba as user1.
file owned by user2.

#chmod 440 /opt/aods/php/mainmenu.php
#ls -l /opt/aods/php/mainmenu.php
-r--r-----    1 user2 group1  870 Oct 30 11:46 mainmenu.php
<<from terminal, user1 cannot write to mainmenu.php>>
<<from samba, ro flag set, user1 cannot write to mainmenu.php>>

#chmod 460 /opt/aods/php/mainmenu.php
#ls -l /opt/aods/php/mainmenu.php
-r--rw----    1 user2 group1  870 Oct 30 11:46 mainmenu.php
<<from terminal, user1 can write to mainmenu.php>>
<<from samba, ro flag set, user1 cannot write to mainmenu.php>>

#chmod 640 /opt/aods/php/mainmenu.php
#ls -l /opt/aods/php/mainmenu.php
-rw-r-----    1 user2 group1  870 Oct 30 11:46 mainmenu.php
<<from terminal, user1 cannot write to mainmenu.php>>
<<from samba, ro flag not set, user1 cannot write to mainmenu.php>>

#chmod 660 /opt/aods/php/mainmenu.php
#ls -l /opt/aods/php/mainmenu.php
-rw-rw----    1 user2 group1  870 Oct 30 11:46 mainmenu.php
<<from terminal, user1 can write to mainmenu.php>>
<<from samba, ro flag not set, user1 can write to mainmenu.php>>


As you can see, the samba server is not checking the group permission bit when setting whether mainmenu.php is read-only.  I have not tested this with the "other" permission bit.
Comment 1 John Medema 2006-10-30 13:28:03 UTC
Sorry, just found out about the "map read only = Permissions" option in smb.conf.  Apparently this behavior is by design, and not a bug.  Sorry about the confusion...
