Summary0007541: Webconfig unable to connect to LDAP - Account system is offline
DescriptionThe _bind() method in /usr/clearos/apps/ldap/libraries/LDAP_Client.php is used to connect to LDAP (OpenLDAP or Samba Directory). From time to time, we have seen systems that have failed to bind to LDAP which in turn generates a "Account system is offline" warning in webconfig. Strangely, the exact same method call using a simple command line test script works just fine.

Turning up the PHP LDAP debug is possible by adding the following to the LDAP_Client.php code:

 ldap_set_option(NULL, LDAP_OPT_DEBUG_LEVEL, 7);

With this debug in place, the following is shown in the /var/log/webconfig/error.log

ldap_bind_s
ldap_simple_bind_s
ldap_sasl_bind_s
ldap_sasl_bind
ldap_send_initial_request
ldap_new_connection 1 1 0
ldap_int_open_connection
ldap_connect_to_host: TCP 127.0.0.1:389
ldap_connect_to_host: getaddrinfo failed: Address family for hostname not supported
ldap_err2string

The "getaddrinfo failed" warning is... odd!

Possible cause is that we're not closing ldap connections...ever.

Try closing connections with __destruct() function...eg:

In /usr/clearos/apps/ldap/libraries/LDAP_Client.php

add the following function after the __construct(..) function:

/**
     * Performs LDAP close.
     *
     * @return void
     */

    public function __destruct() {
        $this->close();
    }
