[otrs] OpenLDAP and Agent UserSyncLDAPMap issues. Not feeling the love.

11 Jun 2008

      Well, I've gotten openldap auth to work but cannot get the 
UserSyncLDAPMap to work.  I've copied the code from Defaults.pm and 
configured for our ldap config.  Have been working on this on and off 
for 3 days, and still no luck.  The code in LDAP.pm that fails appears 
to be trying to pull attribute values from the directory, but adding 
code to put more detail into the log has not been illuminating.  Posts 
ive found in the archive seemto speak primarily to AD issues, which in 
some ways makes me think that OpenLDAP or a more standards-based LDAP 
implementation should be more straightforward.  "Obviously I'm 
mistaken".  I would sure like to get this figured out so we can move 
forward.  Otherwise I will probably have to look at a different system.

This is the value that throws the error: 
Net::LDAP::Entry=HASH(0xace6e04)->get_value(Kernel::Config=HASH(0x9af735c)->Get('UserSyncLDAPMap'.)->{UserFirstname})

The following code block in LDAP.pm is where the problem occurs  (line 
348 is bolded):

foreach my $Entry ($Result->all_entries) {
    $UserDN = $Entry->dn();
    foreach my $Key (keys 
%{$Self->{ConfigObject}->Get('UserSyncLDAPMap'.$Self->{Count})}) {
        # detect old config setting
        if ($Key =~ /^(Firstname|Lastname|Email)/) {
            $Key = "User".$Key;
            $Self->{LogObject}->Log(
                Priority => 'error',
                Message => "Old config setting detected, please use the 
new one from Kernel/Config/Defaults.pm (User* has been added!).",
            );
        }
*        $SyncUser{$Key} = 
$Entry->get_value($Self->{ConfigObject}->Get('UserSyncLDAPMap'.$Self->{Count})->{$Key});*
        # e. g. set utf-8 flag
        $SyncUser{$Key} = $Self->_ConvertFrom($SyncUser{$Key}, 
$Self->{ConfigObject}->Get('DefaultCharset'));
    }
    if ($Entry->get_value('userPassword')) {
        $SyncUser{Pw} = $Entry->get_value('userPassword');
        # e. g. set utf-8 flag
        $SyncUser{Pw} = $Self->_ConvertFrom($SyncUser{Pw}, 
$Self->{ConfigObject}->Get('DefaultCharset'));
    }
}

When logging in it throws the following error:

Software error:

Can't locate object method "get_value" via package "Net::LDAP::Entry" at 
../..//Kernel/System/Auth/LDAP.pm line 348, <PRODUCT> line 4.

For help, please send mail to the webmaster (root@localhost 
mailto:root@localhost), giving this error message and the time and 
date of the error.

Here's the agent portion of my config.pm.
