"Need User" Error message every 15 minutes

[netjess]

Hello,

Every fifteen minutes I am seeing an error like the following:

ERROR: OTRS-CGI-10 Perl: 5.8.8 OS: linux Time: Fri Sep 7 15:28:30 2012

Message: Need User!

Traceback (5364):
Module: Kernel::System::CustomerAuth::LDAP::Auth (v1.38.2.1) Line: 137

Although it appears to be an LDAP error the LDAP authentication to the system seems to be working. As far as I can tell everyone can log into the ticket system.
I also set up some new accounts in Active Directory and they are showing up in the Customer Management list.

This is a flat domain, no remote DC and no sub domains.

Thanks.

The error means something is applying to CustomerUser LDAP authentication without a username.

The relevant code:

Code: Select all

sub Auth {
    my ( $Self, %Param ) = @_;

    # check needed stuff
    for (qw(User Pw)) {
        if ( !$Param{$_} ) {
            $Self->{LogObject}->Log( Priority => 'error', Message => "Need $_!" ); #<-- This would tell you it needs a User or a Password;
            return;
        }
    }

What could be doing this every 15 minutes? ... it's either something in your cron or it's a persistent user on your network.

It (of course) doesn't get far enough to actually *query* your ldap when it doesn't have a username.

Check the timestamps against your apache access log.
