Alex Karasulu commented on DIRSERVER-1183:
------------------------------------------
We may need to have a special compatibility mode flag in the configuration to
switch semantics to handle these cases specifically there by relaxing some of
the 4514 constraints in support of quoted escaped sequences.
I'm thinking this will require alterations to how lookups and search operations
are performed (i.e. when finding the base of a search). The invalidDNSyntax
exception makes me suspect that we may require changes to the DN parser (and
RDN Parser) along with the codec to support this.
> searching with quoted attribute values in a DN causes either noSuchObject or
> invalidDNSyntax

> Key: DIRSERVER-1183
> URL: https://issues.apache.org/jira/browse/DIRSERVER-1183
> Project: Directory ApacheDS
> Issue Type: Bug
> Components: ldap
> Environment: Windows XP SP2, cygwin, ldapsearch 2.3.39, ADS trunk
> Reporter: Matt Parker
> Assignee: Alex Karasulu
>
> searching with a base DN that has quoted values results in noSuchObject. for
> example:
> ldapsearch -b 'cn=foo' ...
> works, but:
> ldapsearch -b 'cn="foo"' ...
> causes noSuchObject. Further, if there is an escaped value inside the quotes,
> invalidDNSyntax occurs:
> ldapsearch -b 'cn=Parker\, Matt' ...
> works, but:
> ldapsearch -b 'cn="Parker\, Matt"' ...
> causes invalidDNSyntax.
> RFC 2253 section 4 (http://tools.ietf.org/html/rfc2253#section-4) clearly
> states that this is legal, but is obsoleted by 4514, which isn't as clear (at
> least to me). Although since most clients that are in use were probably at
> least written against 2253, it makes sense to continue to support quoted
> values for maximum compatibility, even if it's optional.
