I don't think ldap_munge_filter() is adequate any more. Note that filter2bv
doesn't use (?=undefined) for unknown attributeTypes or illegal values any
more, it uses (?<attr>=<value>). This change was made to allow the log
messages to show what the actual offending values were. A better strategy here
may be to walk the Filter tree and look for
(f->f_choice&SLAPD_FILTER_UNDEFINED) before making the search request, so that
no retries are needed.
