There are several problems with your shares.

You have 'guest ok = yes' in a few of them, but guest access will still 
be denied because you do not have 'map to guest = bad user' in [global].

In one share you have 'valid users' and 'guest ok = yes', but this can 
never work (even after you fix the 'map to guest' problem) because the 
user 'nobody' (or whoever the guest user is on AIX) is not in the 'valid 

If this was using an ext4 filesystem (or similar), I would suggest 
adding 'vfs_objects = acl_xattr' to [global], but this is jfs2 on AIX. A 
bit of investigation turned up 'vfs_aixacl2' which I think will do the 
same thing, try running 'man vfs_aixacl2', if this doesn't work, see 

If it does work similar to 'vfs_acl_xattr', you should be able to set 
the permissions from Windows (I am taking it that you do have Windows 
clients) and remove the 'valid users' etc.
