Problems with OpenLDAP x Cacti 0.8.8a

I have a problem authenticating via LDAP where Cacti displays the following message: 

"LDAP Search Error: Unable to find users DN" 

This problem happened after updating Debian 6.0.5 to 7.4, meaning that packages php5, apache2, cacti from 0.8.7g to 0.8.8a, php5-ldap. 
Is there any reported bug regarding the authentication between cacti´s new version the Radius 2.0.4 and OpenLDAP version 2.4.11
