Apache 2.2 not working with LDAP Fail Over Auth

[Muzammel Asghar <muzammel.linux@xxxxxxxxx>]

hi Guys 

I am using apache version Apache/2.2.13 (Unix) on Fedora -11 , and
using ldap as url authentications. I setup my conf in -->
/etc/httpd/conf.d/mydomain.conf with below values

I define only here below the ldap related entries only.


LDAPTrustedMode TLS
LDAPConnectionTimeout 7

<Directory "/var/www/html/test" >


AuthName "Testing Ldap fail over"
        AuthType Basic

        # The LDAP server(s)
        AuthLDAPURL "ldap://ldap1.mydomain.com ldap2.mydomain.com/dc=mydomain,dc=com?uid??"
        AuthBasicProvider ldap
        AuthLDAPBindDN "uid=webcon,ou=WebAdmin,dc=mydomain,dc=com"
        AuthLDAPBindPassword abxxyz

        AuthLDAPGroupAttribute memberUid

 Require ldap-group cn=WEBOU,dc=mydomain,dc=com
        Order Allow,Deny
        Options Indexes FollowSymLinks Multiviews
        Allow from All

        </Directory>


So its working when primary ldap1 server is up but for testing i down
the ldap1 and then do check, so apache not forwarded the auth request
to ldap2. I want to immediate ldap failover if
primary ldap1 is down so it connects  to ldap2 after just some
seconds. For this i can find directive "LDAPConnectionTimeout" in docs
i can try it to define 7 seconds as mention above in conf, but still it fails to connect with
ldap2.

So please kindly give suggestions , what i need extra to make ldap fail over effective.
