Problem with LDAP Plugin in V1.9

I installed the LDAP plugin from Gigatec for Piwik V 1.8.4 and it worked fine. However, when upgrading to Piwik V1.9, the Plugin reports an error.

The error displayed is as follows:

There is an error. Please report the message (Piwik 1.9) and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).
