Bug description:LDAP Referrals
Description:
------------
I am trying to get a php application to follow ldap referrals, specifically
when the local server is a slave, and is used as a read-only server for
performance reasons, but has to write to a master server in order to add,
modify or delete records.
As far as I can tell all I need are three things.
A) Set LDAP_OPT_REFERRALS to 1 using ldap_set_options()
B) Set a callback function using ldap_set_rebind_proc()
C) Create a very simple rebind function.
The problem is that there is no documentation on the subject. For example,
when I check LDAP_OPTS_REFERRALS using ldap_get_options(), I get an answer
of either 0 (when I set it to 0 or false), and an answer of -1 (minus or
dash 1) for any other setting, including 1 and TRUE, and it appears that
the callback function isn't called.
If someone can explain how it is supposed to work enough for me to get it
working, I am happy to provide documentation / examples
Test script:
---------------
ldap_set_option($LDAP_CON, LDAP_OPT_REFERRALS, 1);
ldap_set_rebind_proc($LDAP_CON, rebind_on_referral);
...
function rebind_on_referral ($link_id, $ldap_url) {
$binddn = $_SESSION['ldapab']['binddn'];
$bindpw = $_SESSION['ldapab']['password'];
if (!ldap_bind($link_id,$binddn,$bindpw)) return 1; // Error
else return 0; // Success
}
Expected result:
----------------
callback function should be called, application should rebind to new ldap
server and user should notice nothing
Actual result:
--------------
PHP appears to ignore the referral and ldap_error returns a "referral"
message.
