finally found a workaround for this.

The problem is that any result <= 0 is an error, not only -1:

change line 206 in file ldap/TRLDAPConnection.m to the following:

if (ldap_result(ldapConn, msgid, 1, &timeout, &res) <= 0) {

Just a quick workaround, but it leaves openvpn server intact and running.
