Hi,

I recently tried to build a setup as follows :

Tree : dc=mycompany,dc=com Subtree 1 : dc=subtree1,dc=mycompany,dc=com Subtree 2 : dc=subtree2,dc=mycompany,dc=com

Assuming that my needs are to store subtrees 1 and 2 in separate and remote LDAP servers, I used the LDAP backend. It worked pretty fine, and then I tried to check what was the behaviour if a link went down, or a remote server was unavailable.

Testing, I saw that if I have a 10 seconds timeout for each server, if they're both down, my server spends 20 seconds waiting for the timeouts. I assume that's because the queries are done sequentially and not in parallel.

Is there any way to be able to parallelize the queries and build a "buffer" for each remote backend in order to reconstruct it later, allowing a user not only to use each remote server, but also to find which subtree a user belongs to, without having those kind of problems ?

My test case is pretty simple, but as the final implementation I want to build involves a lot more remote LDAP servers, and as I can't modify the architecture, I'm wondering what are the available solutions.

Thanks,
