Since you are using SuSE I would try to implement NSS (Novell Storage 
Services) on this server.  NSS provides enhanced filesystem ACL's for Linux.  
NSS allows for Novell file access rights to run on a Linux server using the 
standard Linux file system.  NSS sits on top of ReiserFS or ext3.  With NSS 
you should be able to accomplish your third point.   I hope this helps a 
little.

Hi all,

I have a requirement to secure the access to files at the filesystem. The
Operating system used will be a SuSE linux box.

1. Each file created in a directory inherits the access rights of the
directory
2. Each directory created inherits the access rights of the directory
3. A file or directory created by a user who is member of group A,B and C
should be readable by another user if he/she is member of either group A
or B or C.

The first two points can be implemented with the default directive of the
linux filesystem acl's.

Anybody with an idea on how to implement the third point would be great.

kind regards
lars
