Based on the connection properties in LDAP Admin (neither the SSL or TLS 
checkboxes are enabled) the connection should be unencrypted... A netstat 
confirms that LDAP Admin is connecting to port 389 on the server.

Hi,

I'm hitting a wall trying to troubleshoot an issue with LTB self service 
password...

Here's an excerpt from the apache2 error log (debug mode enabled):

error 53 (Server is unwilling to perform), referer:

I've tested using LDAP Admin (http://www.ldapadmin.org/) and I can change the 
same account password that failed with LTB SSP. I'm connecting to the same AD 
DC too and I don't need to use a secure connection (LDAPS), just unencrypted 
LDAP on port 389.

Here are the relevant entries in my config.inc.php file:

$ldap_url = "ldap://ip_address_of_ad_dc";<ldap://ip_address_of_ad_dc>;
$ldap_binddn = "cn=ldapuser,cn=Users,dc=domain,dc=ext";
$ldap_bindpw = "ldapuserpasswd";
$ldap_base = "dc=domain,dc=ext";
$ldap_login_attribute = "uid";
$ldap_fullname_attribute = "cn";
$ldap_filter = 
"(&(objectClass=user)(sAMAccountName={login})(!(userAccountControl:1.2.840.113556.1.4.803:=2)))";

$ad_mode = true;
$ad_options['force_unlock'] = true;
$ad_options['force_pwd_change'] = true;
$samba_mode = false;

$who_change_password = "manager";

All other settings are default.

Any ideas?

Thanks!
Hi,

Are you sure that ldapadmin does not use TLS when connecting on port 389 ?
Because I believe that having an encrypted connection is required in order to 
change a password in AD
(it works on ldaps, I don't know for sure for TLS, but I would not be surprised 
it does to).

Regards,
