You have to be authenticated in the administrator backend.
Here you have to browse to the control center:
- In configuration click on portal settings
- Select authentication
- Select ldap
- select add server
- input following code in server name

Value for ldap server name field:
Name_of_ldap_server<script>alert("XSS")</script>

The script is inserted to the configuration page persistent until the ldap server is deleted from database again.
