LDAP authentication problem with server down

[agz]

Hi all,
I have a problem in my Alfresco 4.0.e with LDAP authetication:
I configured an authentication chain with many ldap servers

<em>alfresco-global.properties</em>

authentication.chain=ldap_hq1:ldap-ad,ldap_hq2:ldap-ad,ldap_hq3:ldap-ad,ldap_pos1:ldap-ad,ldap_pos2:ldap-ad,ldap_pos3:ldap-ad,ldap_obs1:ldap-ad,ldap_wh1:ldap-ad,alfinst:alfrescoNtlm
‍‍‍

I have the synchronization not active:

ldap.synchronization.active=false
‍‍‍

For each server of chain I created the folder in ../extension/susystems/Authentication with the parameter of server.

When the servers are up the authentication works fine…but there is a problem with chain, this is the case:
I set, for the first ldap server in chain, an IP not available (like a server not reachable)

At Alfresco startup it shows an error

Unable to connect to LDAP Server; check LDAP configuration
 javax.naming.CommunicationException: 192.168.228.32:389 [Root exception is java.net.ConnectException: Connection timed out]
   at com.sun.jndi.ldap.Connection.<init>(Connection.java:210)
‍‍‍‍‍

and this is correct!

<strong>The problem affect users that try to login for the first time (that are not still present in Alfresco):they are not able to access!</strong>

The log return me a Login Failed and the user is not able to access
