Unable to access Phpldapadmin with admin account

I installed Phpldapadmin in Debian Wheezy. I followed all the steps to configure Phpldapadmin as given in https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-a-basic-ldap-server-on-an-ubuntu-12-04-vps. I’m able to login as Anonymous and but not as Admin.

Here is /etc/phpldapadmin/config.php

$servers->newServer('ldap_pla');
$servers->setValue('server','name','IN-BAN-AS01 LDAP Server');
$servers->setValue('server','host','192.168.x.x');
$servers->setValue('server','port',389);
$servers->setValue('server','base',array('dc=cti,dc=paris'));
$servers->setValue('login','auth_type','cookie');
$servers->setValue('login','bind_id','cn=admin,dc=cti,dc=paris');
$servers->setValue('login','bind_pass','xxx');
$servers->setValue('server','tls',false);

After modifying config.php, restarted apache service /etc/init.d/apache2 restart

Here is the error, when I login with admin account

“Unable to connect to LDAP server My LDAP Server Error: Invalid credentials (49) for user error Failed to Authenticate to server Invalid Username or Password.”

Where else I need to modify, to access admin account ??
