The error seems to vary depending on the version of Net::LDAP. 
Alternatively it may log:

[root at entry log]# tail -f /var/log/zimbra.log | grep -i amavis | grep -i 
error
Nov 14 11:33:14 entry amavis[24329]: (24329-16) (!)lookup_ldap: do_search:
failed: LDAP_LOCAL_ERROR

So it should account for that as well:

    } elsif ($error_name !~ /^LDAP_(?:BUSY|UNAVAILABLE|UNWILLING_TO_PERFORM|
 
TIMEOUT|SERVER_DOWN|CONNECT_ERROR|OTHER|LOCAL_ERROR|OPERATIONS_ERROR)\z/x) {
      die "do_search: failed: $error_name\n";
