Bad LDAP coding, bad Application, but....maybe the LDAP Implementation?

Posted by Gavin Henry on
OpenLDAPSuretec It is true that Poorly written LDAP[?] code can really affect your Portal, Suretec have seen it a few times:

A programmer who hadn't had much exposure to LDAP decided it best to do a base level search, for example, using ldapsearch:

CODE:
ldapsearch -x -b 'dc=suretecsystems,dc=com' '(objectclass=*)' -H ldap[?]://127.0.0.1


he retrieved *everything*, then did all the searching/filtering etc. locally in the client! What's the point of a Directory Server!?!

Our partners Symas have also talked about similar encounters, mainly with Sendmail.

It all comes down to the level of LDAP understanding a programmer has.

Or could it actually be the Directory Server implementation, namely Oracle Internet Directory (OID)?

I know OpenLDAP wouldn't slow an app down like this, because it's very fast..very very fast ;-)

James on :

*This is the same argument in favor of server-side search and VLV.

James on :

*Server-side search *ordering*, even.

Gavin Henry on :

*Not quite, as that code can be controlled by the programmers with LDAP knowledge, i.e. the ones developing server side.

This is bound to be more efficient than the client side programmer.

James on :

*Yeah, that's my point. But the OpenLDAP devs don't seem to share that view http://www.openldap.org/lists/openldap-software/200711/msg00184.html

Gavin Henry on :

*I never said it was a good thing.
