CONNECTING FROM A SERVERS POOL

[Alberto L. C. (Pexego) <al...@pe...>]

Hi all! Me and a workmate are currently working in an approach of 
connecting to different LDAP servers (each one is a replica of another) 
because of fault tolerancy purposes.
So, first thing we did was modifying the *__init__* method of 
SimpleLDAPObject class (ldapobject.py file) adding a new attribute 
"pool" which contains the list  of servers passed as param in 
*initialize* method as a string. So, attribute .*_l *changes to:
    self._l = 
ldap.functions._ldap_function_call(_ldap.initialize,self._pool[0])

Then, in *_ldap_call *we introduced a /while/ loop surrounding all code 
with a boolean condition set to False. When *"func"* call fails raising 
a "SERVER_DOWN" exception, we remove URI from pool and create a new 
ReconnectLDAPObject instance with self._l attribute pointing to next 
LDAP URI in pool.

The problem we're actually facing is that when *func *calls raises a 
SERVER_DOWN exception (with, for example, a *search_s* operation) the 
code behaviour is correct when URI is wrong, but when LDAP URI is right 
the func calls stills raises an exception...Is this because of what is 
explained in the beginning of ReconnectLDAPObject class (that 
synchronous methods like search_s() automatically tries to reconnect 
when LDAP server is down)?.

Are we pointing in the right direction?

Thanks a lot in advance.
