Description:
------------
Recently at my site they started to upgrade some directory servers and
suddenly stuff started to break. All of them PHP'ish. All LDAP searches
broke with "Operations Error". Doing the same queries with ldapsearch
(openldap commandline tool) everything looked fine except that I could
imagine something going on with the result as I got 'ref:
ldap://foo.bar.com/ou=foo,o=bar' back in the chunk coming from the
server.
I found a 2-year old workaround for it here: (Surprisingly works
flawless.)
http://groups.google.se/groups?q=LDAP_OPT_REFERRALS+%2Bfollow+referrals&hl=en&lr=&ie=UTF-8&oe=UTF-8&safe=off&selm=20011226190121.22738.qmail%40php2.chek.com&rnum=1
Reproduce code:
---------------
foreach($ldaphosts as $ldaphost)
{
if( !$fail && !$success)
{
if( $connect = @ldap_connect($ldaphost) )
{
if( $bind =
@ldap_bind($connect,$ldapbinddn,$lda
pbindpasswd) )
{
$filter =
"($ldapuserattr=$username)";
$search =
@ldap_search($connect
, $ldapbasedn, $filter, array('cn'));
$info =
@ldap_get_entries($connect, $sea
rch);
if($info[0]['dn'])
{
if(ldap_bind($connect,
$info[0][
'dn'], $password) )
{
$success = 1;
} else {
$fail = 1;
}
} else {
$fail = 1;
}
}
}
ldap_unbind($connect);
}
}
Expected result:
----------------
ldap_search() to return an ldap search resource to pass on to
ldap_get_entries
Actual result:
--------------
ldap_search(): Search: Operations error
