We're trying to set up an SFTP entry trough the gateway. Therefore SSH key authentication should be possible, but at the moment (as it seems) it is not possible to get the SSH key from an variable to authenticate it to an LDAP.
Could you tell me if and how this is possible. Otherwise we would like to submit a feature request. For most of the other variable's this is possible. (for example the "extract attributes from certificate" assertion).
