Hmm.
Well, your line is definitely wrong.
isset() only checks if a variable has a value at all.

<code>

if (isset($foo)) {
   bar();
} else {
   foobar();
}

</code>

But what you obviously try to do is check the VALUE of the variable,
not the existence of the VARIABLE itself.
Just do

<code>
if ($_SESSION['SESSION_UNAME'] != $user) {
   foo();
}
</code>
