My guess is that it's SELinux.  Try doing the following:

1.  Create 'dir' as before.
2.  As the user, run the following shell commands:

LC_ALL=C
export LC_ALL
ln dir/a/symfile dir/b

Assuming this fails, look at the output of:

strace ln dir/a/symfile dir/b

My guess is that you'll see something like this:

linkat(AT_FDCWD, "dir/a/symfile", AT_FDCWD, "dir/b/symfile", 0) = -1 
EPERM (Operation not permitted)

If so, the problem would appear to be in SELinux itself.
