User registration in biller direct 6.0

Hello everybody,

we want to use the biller direct in ECC 6.0 and we installed and configured the BD, so that it works fine. Now I tried to create new user about the bd/createuser.sap form. And there I get a new Office notification. I configured the messeagetyp and number 71 to create users. Then in the Action Box the steps display form, check user data are ok with execute the step create user, e-mail I get an error E338(>4) with "Error communication with the JCO RFC server" and "RFC destination JCO_LDAP_RFC_DEST does not exist."

So my question is: Where I have to set and configure a JCO RFC server and the destination?

Thanks for any help,

regards

Christian
