[ApacheDS] lost with decision where to implement custom permission

[Garbage <ga...@gmx.de>]

I tried to build a working custom partition implementation for last days. I started with 1.5.7 but then found out that the working example I intended to base on does no longer compile because of some API changes. Because of this I switched to 1.5.5 and managed to get the example running (not that difficult, I have to admit ;-))

Unfortunately I don't have enough background knowledge to be able to extend the HelloWorldPartition example.

I'm willing to learn and invest time but need expert advice if I should continue with 1.5 or 2.0. In addition I will need some guidance. In exchange for that I can offer you to update the docs for custom partitions.

Thanks for this confirmation

You sure can use M7.

I believe I can use the released milestone 7 because parallel reads / writes don't exist in my scenario. Or are there any other issues I should keep an eye on ?

No. I'm sad to say that but M7 still have a huge bug that we are 
tracking. Not that you'll won't get a working server, but in some cases 
where concurrent writes and searches are done, you are very likely to 
get some failures during the searches. More than that, the database can 
get corrupted.

We exactly know what is going wrong here, and we already have a fix, but 
this is in a branch, and we are currenly merging this branch into trunk, 
which is all but easy.

M8 will solve this issue, and we expect to get it released ASAP. In the 
mean time, you can use the directory/apacheds/branches/apacheds-txns 
branch whch solve the issue.

You can still work on the trunk, until M8 get released.

Just keep tuned, we are doing our best to get back to some solid and 
reliable server soon.

Thanks for that information, this might be the explanation why I got lost in the transition from 1.5.5 to 2.0: I simply didn't understand what changes were to see. So I will head for 2.0, I expected that answer ;-)

But I still have these questions:

1. Can M7 be considered stable enough for giving it a chance in a productive system?

I only need ApacheDS to sit there and wait for incoming connections and forward them to my custom partition. There is no need for replication and all the other fancy stuff ApacheDS is able to do.

2. Where should I start off in order to create a partition that uses data from my java objects and sends it back to the client ?

Some details to explain what I'm after: I need to integrate a google search appliance with at least three different directories. One is based on LDAP, one can be accessed via a web service and the other has a SQL interface. I discussed this topic on stackoverflow and even posted a question on the developer list of ApacheDS, back then I intended to use an interceptor but now I believe that a custom partition will be a much better solution. The easiest way to integrate these directories will be a LDAP interface because the GSA is able to connect to LDAP, the queries can be configured.
The main idea is to write a partition that listens on access to ou=user and answers to queries that follow this pattern: (username=johndoe). It should then deliver the two attributes distinguishedName and mail. 
In a second step the GSA will send a query that looks like this: (member=distinguishedName). The expected answer will then be a list of dns of groups the user belongs to. This information will be delivered by my java code and can be considered a blackbox. Just think of it returning a string array of groups in ldap format.

Definitively go for 2.0. The API has changed a lot, but this is 
(hopefully) for the best.

Sadly, the documentation is not following the code modification pace :/

Do you have any specific question ?

Sorry, I either mistyped or became a victim of auto correction: I meant PARTITION
