I reproduced a problem where connecting to an LDAP server, and then binding to an 
address I know to exist and work will perform perfectly.

Within the same script, following an unbind (as I don't need the connection to be 
binded any more), using ldap_bind(..) again [even the same user and password as 
the original] would result in a fail.

Test script:
---------------
// Assume variables all set in working order below...

$ldapconn = ldap_connect($ldaphost, $ldapport) or die("Could Not Connect to $ldaphost");

$ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass);
// bind successful

ldap_unbind($ldapconn);

$ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass);
// second bind unsuccessful!?

ldap_close($ldapconn);
// close ldap connection

Expected result:
----------------
after unbind, the bind function will work normally

Actual result:
--------------
after unbind, bind function always fails.
if initial bind has not been unbinded, then subsequent bind (even for 
same/different user) will work correctly.
