I'm kind of an ldap newbie, but after reading this thread several
times I have no idea what you are trying to do. Are you trying to
write a new storage system for apacheds? Or are you trying to use
ldap as a persistence store for an application that deals in java
objects? Or something else entirely? Which version of apacheds are
you using? To me, your first posts look like you are trying to
replace the storage apacheds uses, which AFAIK is fairly non-trivial,
but your latest post looks like you want help installing a bunch of
new schemas into apacheds, which is pretty easy.
thanks

Since i have problems with the partition creation and i need help
urgently to have an example, I'm willing to offer ($150 via paypal
or similar) to have this example together with attribute mapping
which allows me to have a custom schema.

Woudl it be a couple of weeks, may be...
Anyone ?
Sorry :(

Hi,
Basically i have a couple of days to solve this so its quite urgent
for me.

ok, get it. So you want your application to be the backend, basically.
I know this is possible, but I think you will have to implemant
something like 11 interfaces to make it works.
Hopefully, Alex may give you more informations about it. I also
have to look at this part, and ths could be the perfect occasion.
Is this urgent ?

Hi,
Im interesting in using ADS as a mapping between LDAP and my
application. to get LDAP support. so basically just the frontend.
I have looked arround for examples on how to write the backend but
i havent realy found soemthing usefull.
BR / Johan Asterholm
2007/1/22, Emmanuel Lecharny <[EMAIL PROTECTED]>:
ok.
But do you need ADS at all? Or are you just interested by storing
DNs into a backend ?

Hi,
By backend can store up to several milion records but its quite
fast in answering (about ~20 MS) when having 2 milion records. The
application will handle caching itself so no caching wold be
necessary. Basically what I'm looking for is just an example for
writing my backend.

Hi,
the backend is using its own structure atm. It's based on JDBM,
which is a B-tree storage.
The DN are also stored in a B-Tree, and this is not necessarily
optimal. We may want to go for a H-tree instead of a B-tree for
these DN (B-tree and H-tree storages are available in JDBM)
So basically, it's just a question to associate a H-tree to the DN
storage.
Ok, this is theory. In the 'real world', this would need more
analysis, and we must evaluate the impact of such a modification on
the code base.
Now, I have a question : how big is your data set ? If it's a few
thousnads, there would be a very little increase in performance
doing that : you have to consider that the cache system will very
quickly keep in memory all the DN of your database. (you might want
to increase the cache size for this kind of objects in your
partition :
...
<property name="indexedAttributes">
<set>
<bean
class="org.apache.directory.server.core.partition.impl.btree.MutableIn
dexConfiguration">
<property name="attributeId" value="
1.3.6.1.4.1.18060.0.4.1.2.1" />
<property name="cacheSize" value="100" />
</bean>
...
In this default configuration, 100 DNs are kept into the cache.
Just increase it to fit your needs.
If in cache, grabbing a DN is really fast, wether you use H-tree or
not.
You will just have to consider if this would be of interest to
modify the backend (with all the burden it suppose) instead of
increasing the cache. And this is again a question of how many DN
will you have.
I hope this help.
Feel free to go further, we really have this Hashing in our radar.

Hi,
I'm trying to develop LDAP integration towards an application, but
I have a hard time to understand how it all should work.
To learn how it should be done I'm trying to develop a backend
which works towards a HashMap where the hash Map includes a key
(Identifier) And then another hashmap with attributes (They are not
"Attributes" but simply String names of the attribute). I prefer
this way since this is quite similar to what i need to do when
integrating towards or application.
so searching for uid=1,ou=user,cn=example,cn=com would point to a
row in the hashmap, but ou=user,cn=example,cn=com is static.
Is there any example where a simple backend like this is done?
Maybe not with a HashMap but something similar?
This would help me tremendously.
