[squid-users] Failover to second LDAP server with squid_ldap_auth

Dear Squid-Users

I tried to figure out, how to setup up my squid auth helpers
to use a second LDAP server if the first one is unreachable.

 From several postings on this mailing list I thougth that
squid_ldap_auth and squid_ldap_group which come with the
squid source are able to support this option:

e.g. http://www.squid-cache.org/mail-archive/squid-users/200412/0290.html

And reading the man page also lets me believe that I can just pass
two IP addresses to make it work:

http://linux.die.net/man/8/squid_ldap_auth
---snip---
-h ldapserver
     Specify the LDAP server to connect to. Servers (!) can also be specified last on the command line.
---snap---

So I tried this on the command line:
# squid_ldap_auth -b "dc=some,dc=com" -f "sAC=%s" -D "cn=ad,ou=Users,dc=some,dc=com" -w "***" -c 2 -t 2 -p 3268 -h "10.0.0.1 10.0.0.2"

This works fine if the first IP (10.0.0.1) is answering properly to my
LDAP requests but it doesn't if only the second host (10.0.0.2) is
reachable and answering LDAP requests.

Instead I get the following error message:
> someone ***
> squid_ldap_auth: WARNING, could not bind to binddn 'Can't contact LDAP server'
> ERR Success

I'm using Squid Cache: Version 2.7.STABLE4.

What am I doing wrong?

Best Regards,
Christoph G.
