The “calc_val” was failing when LemonLDAP::NG was disabled because
“authWebName” can't be used.
We shouldn't force “eolesso_adresse” when LemonLDAP::NG is disabled,
the user must be able to set whatever value she wants.
* dicos/71_lemonldap_ng_scribe.xml: fill the “eolesso_adresse” and
freeze it when LemonLDAP::NG is enabled.
