[horde] username always null in prefs_init hooks with LDAP auth

[Guenter Bartsch]

Hi,

we're trying to apply

http://wiki.horde.org/LDAPHooksHorde5

to our horde setup which is using ldap authentication to set up the
default from email address for all users. unfortunately it doesn't
work because $username is always null when the hook is called:

Sep 30 10:37:02 mail2 HORDE: [horde] prefs_init, pref=from_addr [pid 30196]
Sep 30 10:37:02 mail2 HORDE: [horde] prefs_init, username= [pid 30196]

this is the code we have added to generate the log output pasted above:

<?php
class Horde_Hooks
{
    public function prefs_init($pref, $value, $username, $scope_ob)
    {

        $logger = $GLOBALS['injector']->getInstance('Horde_Log_Logger');
        $logger->info('prefs_init, pref=' . $pref);
        $logger->info('prefs_init, username=' . $username);

anybody got any idea how to debug this further?

thanks,
