Hi everybody. I managed to keep developing til now but I'm desperate
today...
I guess this is easy stuff for people with some experience in OpenLDAP:
I just need to perform a search. I am inside an overlay's response and
I need to search for some entries. The question is:
- How do I set the SlapReply rs?
- I guess I need to create an Operation. How do I do that?
- I have to call some search function. I found some searching functions
taking an Operation* and a SlapReply* as parameters (like do_search and
others) but I don't know which is the one I need.
If you could just drop an example (I guess that it is some 5 lines). I
just have to perform a search with a filter I know (and have constructed
as a string). Should be something like:
char *filter = "objectClass=Aclass";
// SlapReply *rs initialization
// Operation *op initialization
// Perform search( op, rs )
Maybe I'm far from the solution...
I would be very pleased if you could help me with this, I'm just going
mad jumping from one place in the code to another...
If this message should be sent to another mailing list, just tell me and
I'll resend it correctly.
Indeed, this may need some knowledge of OpenLDAP internals to be
accomplished correctly. I believe slapd's code and existing overlays
provide quite a bunch of examples in many cases. The general rule is
that to initialize those structures, from within a function that
receives a pointer to an Operation, something like
function( , Operation *op, )
{
Operation o = *op;
SlapReply r = {0};
/* ... */
search(&o, &r);
/* ... */
return ;
}
is fine, provided you don't modify the original values by reference
(i.e. the contents of pointers) but by value (i.e. replace pointers with
pointers to data that is private to your overlay).
It's hard to tell what you can or you can't modify, because it depends
on the type of operation and on what you need to do.
Hope this helps.
