Hallvard,
4.5.1. Search Request
Filter ::= CHOICE { and [0] SET OF filter Filter, or [1] SET OF filter Filter,
Another change I do not remember from the list: The SIZE (1..MAX) was removed from the ASN.1 grammar (though the textual description still requires at least one component). Why?
I don't remember if it has been discussed on the list, but one reason for the change is in anticipation of Kurt's true/false search filters draft becoming a proposed standard. If the SIZE constraint isn't there then there is no need to revise the ASN.1 for LDAP (and it is one less thing I need to fiddle for XLDAP).
Regards, Steven
