Perl LDAP problem?

[localzuk]

I am trying to make use of RT and the ExternalAuth module for it. However I am getting this error:

error: Can't coerce array into hash at /usr/local/share/request-tracker3.6/lib/RT/User_Vendor.pm line 176.

The corresponding chunk of code in the User_Vendor.pm file is below:

my $base            = $config->{'base'};
            my $filter          = $config->{'filter'};
            my $group           = $config->{'group'};
            my $group_attr      = $config->{'group_attr'};
            my $attr_map        = $config->{'attr_map'};
            my @attrs           = ('dn');

            # Empty parentheses as filters cause Net::LDAP to barf.
            # We take care of this by using Net::LDAP::Filter, but
            # there's no harm in fixing this right now.
            if ($filter eq "()") { undef($filter) };

            # Now let's get connected
            my $ldap = $self->_GetBoundLdapObj($config);
            next unless ($ldap);

            $filter = Net::LDAP::Filter->new(   '(&(' .
                                                $attr_map->{'Name'} .
                                                '=' .
                                                $self->Name .
                                                ')' .
                                                $filter .
                                                ')'
                                            );

I'm not a perl guru, so can anyone give me any clues as to what the problem is? Net::LDAP is installed as it should be.

Check the obvious bits first - are you trying to pass an array to a function in User_Vendor.pm instead of a hash?

It's not my code, so I haven't the foggiest... And I think it is complaining that a hash is being sent instead of an array.

However, I can safely say I don't need to know about this any more, as I now have external authentication working using Apache PAM, SAMBA/Winbind and WebExternalAuth in RT.
