I am having a problem with my LDAP Integration.  I have successfully added my DC, and imported users.  
However when I try to enable LDAP authentication nothing happens.  

Reviewing serverout0.txt I see that when I try to enable LDAP auth I get the following errors:

[11:19:29:320]|[07-06-2015]|[com.manageengine.servicedesk.servlet.ClientLogServlet]|[SEVERE]|[26]|: Login user(id):3, Error occurred-->Uncaught TypeError: Cannot read property 'innerHTML' of null, in file name: http://[address redacted for security]:8080/ImportLdapUsers.do?module=enableLdap&ldapauth=true, at line number:106|

[11:09:19:622]|[07-06-2015]|[com.manageengine.servicedesk.servlet.ClientLogServlet]|[SEVERE]|[35]|: Login user(id):3, Error occurred-->Unable to get property 'innerHTML' of undefined or null reference, in file name: http://[address redacted for security]:8080/ImportLdapUsers.do?module=enableLdap&ldapauth=true, at line number:106|

How can I resolve this problem?
