When searching for Chinese names in the "to:" field under Thunderbird, I see asserted_value_validate_normalize() not returning LDAP_SUCCESS in filter.c. This is because the "mail" attribute in core.schema is of type "IA5 String" but the Chinese name falls outside the character set.
The work around I have is to modify the "mail" attributetype in the core.schema from:
attributetype ( 0.9.2342.19200300.100.1.3 NAME ( 'mail' 'rfc822Mailbox' ) DESC 'RFC1274: RFC822 Mailbox' EQUALITY caseIgnoreIA5Match SUBSTR caseIgnoreIA5SubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.26{256} )
to:
attributetype ( 0.9.2342.19200300.100.1.3 NAME ( 'mail' 'rfc822Mailbox' ) DESC 'RFC1274: RFC822 Mailbox' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{256} )
Dieter Klünter pointed out on the openldap-technical mailing list that this breaks RFC-5322. However Charles T. Brooks suggests:
Non-english character sets are going to become part of hostnames and DNS. That's inevitable.
Mail addresses are based on DNS hostnames.
Ergo, mail attributes will one day need to support all possible characters.
Given that, I think the above changes to core.schema seem worthwhile.
