- The new iRedMail Open Source Edition does not include with phpldapadmin.
- So then, you need to install it manually.
- For Centos 7 you may yum install phpldapadmin
- By default configuration phpldapadmin you may not able to logon into the openldap.
- To do that you may change this value in /etc/phpldapadmin/config.php at line 399
$servers->setValue('login','attr','uid');
should be
$servers->setValue('login','attr','dn');
