    Hi,

    
    I think the error is not with squid version, it might be the
    connection problem between proxy server and  LDAP server. Please,
    check the reachability of LDAP server from the proxy server and also
    Just check the DNS configuration whether you have correctly
    configured it in proxy server.  

    
    First, You can try the test connection to the LDAP sever from the
    terminal, if it succeed then you can modify the squid configuration.
    I have given a sample one, modify the domain and credentials
    according to your one and try.

    
            [root@test ~] #  /usr/lib64/squid/squid_ldap_auth -R -b
    "dc=test,dc=com" -D "CN=admin,DC=test,DC=com" -w "password" -f
    sAMAccountName=%s  -h 192.168.195.195

            username password

            OK

    
    If you get the output "OK", then you have successfully tested the
    connection with the LDAP server. If you cannot establish the
    connection with LDAP server, then you will get the same error.

    
            [root@test ~] #  /usr/lib64/squid/squid_ldap_auth -R -b
    "dc=test,dc=com" -D "CN=admin,DC=test,DC=com" -w "password" -f
    sAMAccountName=%s  -h 192.168.195.195

            username password

    contact LDAP server'

        Hi
         
        I have squid installed and trying to
          contact Ldap. 
         
        Below command is working for older squid,
          but not new one and both server are Redhat 6.5 (Santiago)
         
        auth_param basic program
          /usr/lib64/squid/squid_ldap_auth -b
          ou=xx,dc=xx,dc=xx,dc=xx,dc=xx -f (&(cn=%s)(objectClass=*))
          -u cn -s sub -P -c 5 -t 5 -R -a never -D
          cn=Lookup,ou=xx,dc=xx,dc=xx,dc=xx,dc=xx -w xxxxx mydomain
         
         
        error message is:
         
        squid_ldap_auth: WARNING, could not bind to
          binddn 'Can't contact LDAP server'
        squid_ldap_auth: WARNING, could not bind to
          binddn 'Can't contact LDAP server'
        squid_ldap_auth: WARNING, could not bind to
          binddn 'Can't contact LDAP server'
         
        to stop type isse, I have scp the
          squid.conf from older one to new one? And restart the squid;
          and also tried to copy firewall configuration over to new box,
          in case some firewall issue. It is still not help. 
          
         
        Could any one advice me what is the
          possible issue related? 
          
                                                                                                           
        Any comments will be appreciated
         
        Thanks in advance
