From: bugs dot php dot net at phrenetic dot to Operating system: RedHat 7.1 PHP version: 4.3.3 PHP Bug Type: LDAP related Bug description: Unable to handle Active Directory referals (W2k3)
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 -- Edit bug report at http://bugs.php.net/?id=25921&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25921&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25921&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25921&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25921&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25921&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25921&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25921&r=support Expected behavior: http://bugs.php.net/fix.php?id=25921&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25921&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25921&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25921&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25921&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25921&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25921&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25921&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=25921&r=float
