Ok, this isn't so cool anymore, "attribute provided more than once" is breaking more of my client code when run against 2.0.23.
You have to fix your client code.
Looking in servers/slapd/add.c there is a new line
if (!repl_user) {
*text = "attribute provided more than once";
return LDAP_TYPE_OR_VALUE_EXISTS;
}
This protects you from violating the X.500 data model.
Ciao, Michael.
