Slapadd stops at that point, but does not print an error message. Oops, the library has provided an error message for this instance since 2.4.5beta (September 2007) but slapadd wasn't enabling the display of that message by default. This is now fixed in HEAD. -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Re: (ITS#6101) Uninitialized SlapReply components

It's not always clear to me which code is responsible for initializing SlapReply anyway. Fixed two other simple cases: - result.c:send_ldap_disconnect() should reset rs->sr_rspdata. - sasl.c: should (re)set rs->sr_sasldata before doing send_ldap_sasl(). -- Hallvard

Re: (ITS#6197) ldap_err2string()/ldap_perror() strangeness
by h.b.furuseth＠usit.uio.no 07 Jul '09

Also ldap_err2string(), unlike ldap_perror(), does not pass messages from recognized result codes through _() - i.e. the optional gettext(). I'll fix that too. -- Hallvard

Interoperability is not a requirement for slapd configuration elements. However, any shortname already present in RFCs would be obvious first choices. E.g., "passwdModify" (RFC 3062, section 2) and "whoami" (RFC4532, section 2) (derived by dropping the letters "OID" from the name of the OID definition). Or just accept any oidmacros, as some of the other config items already do. On that score I believe we should promote more pervasive use OID macros instead of numeric OIDs, because that greatly enhances comprehension by human administrators. I believe we should define macros for all of the syntaxes etc. already in common use in slapd and document them, guaranteeing that they will be available for everyone else who uses OpenLDAP to also take advantage of them. (Note that back-config already has several hardcoded, but they're decorated with "OM" prefix and not documented for public consumption. For real use they should be unadorned, using plain names such as "integer" or "directoryString" ...) -- -- Howard Chu CTO, Symas Corp. http://www.symas.com Director, Highland Sun http://highlandsun.com/hyc/ Chief Architect, OpenLDAP http://www.openldap.org/project/

Yes, the OpenLDAP project can maintain a proprietary list like all other LDAP vendors do. :-( Probably that's another topic for cross-vendor coordination... Ciao, Michael.
