DFN LDAP benutzen 2

You specify that your search should be inside the ldap-DFN-PKI address book and you want to make an extended search.

DFN LDAP benutzen 3

Your search criterium is "RA Postfach RWTH" anywhere inside the "Common Name" field of the DFN-PKI user certificates.

DFN LDAP benutzen 4

You have found the recipient you are looking for, you now need to save them in your own contacts.

DFN LDAP benutzen 5

Please note the user added "(DFN)" part in the Name. This helps you distinguish your contact as one imported from the DFN-PKI LDAP address book, i.e. with a user certificate (and a public RSA Key associated to it).
