The OpenLDAP server with address openldap.tue.nl is not functioning well and will be discontinued.
Use the Active Directory server instead.
Description: "TU/e Active Directory" (w/o quotes; or whatever you prefer) Search base: "DC=campus,DC=tue,DC=nl" (w/o quotes) Scope: Subtree (default) Server Address: campusdc1.tue.nl Server Options Port: 389, do not Use SSL (defaults) Authentication: Simple User name: TUE\<your NT-account name> Password: <your password>
Thanks to Tom Verhoeff for figuring this out. Aug 2014
