#39362 [NEW]: imap_open retries 3 times on failed auth

From: askalski at gmail dot com Operating system: Linux PHP version: 5CVS-2006-11-03 (snap) PHP Bug Type: IMAP related Bug description: imap_open retries 3 times on failed auth Description: ------------ imap_open will retry 3 times on bad credentials. Some IMAP or POP servers delay on successive bad logins, making a failed imap_open take very long. Worse, some servers will lock the user out because of repeated failed login attempts. Somewhere during module initialization, this call needs to be made: mail_parameters(NIL, SET_MAXLOGINTRIALS, (void *) 1); Reproduce code: --------------- imap_open("{mailserver/pop}", "user", "badpass"); Expected result: ---------------- It should try logging in only once. Actual result: -------------- It tries logging in three times (watch with a packet sniffer or strace). write(0, "AUTH LOGIN\r\n", 12) = 12 ... read(0, "-ERR Bad authentication\r\n", 8192) = 25 write(0, "AUTH LOGIN\r\n", 12) = 12 ... read(0, "-ERR Bad authentication\r\n", 8192) = 25 write(0, "AUTH LOGIN\r\n", 12) = 12 ... read(0, "-ERR Bad authentication\r\n", 8192) = 25 write(0, "QUIT\r\n", 6) = 6 read(0, "+OK Sayonara\r\n", 8192) = 14 write(1, "\nWarning: imap_open(): Couldn\'t "..., 104) = 104 -- Edit bug report at http://bugs.php.net/?id=39362&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=39362&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=39362&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=39362&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=39362&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=39362&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=39362&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=39362&r=needscript Try newer version: http://bugs.php.net/fix.php?id=39362&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=39362&r=support Expected behavior: http://bugs.php.net/fix.php?id=39362&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=39362&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=39362&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=39362&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=39362&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=39362&r=dst IIS Stability: http://bugs.php.net/fix.php?id=39362&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=39362&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=39362&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=39362&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=39362&r=mysqlcfg
