It is definitely related to the filter. The problem is in UserExists
which ensures that the user actually exists in the user database, and is
run once for each specified database iirc.
Shortened for simpicity:
#################################################################
my $config = $RT::ExternalSettings->{$service};
my $filter = $config->{'filter'};
if ($filter eq "()") { undef($filter) };
if (defined($config->{'attr_map'}->{'Name'})) {
# Construct the complex filter
$filter = Net::LDAP::Filter->new(
'(&' . $filter . '(' . $config->{'attr_map'}->{'Name'} . '=' .
$username . '))');
}
my @attrs = values(%{$config->{'attr_map'}});
# Check that the user exists in the LDAP service
$RT::Logger->debug( "LDAP Search === ",
"Base:",
$base,
"== Filter:",
$filter->as_string,
"== Attrs:",
join(',',@attrs));
my $user_found = $ldap->search( base => $base,
filter => $filter,
attrs => \...@attrs);
#################################################################
The filter information is taken directly from your config and used to
build a filter object. There is then a debug message that uses as_string
to print out the filter object. In your case, $filter is not a defined
object and so the as_string call is invalid.
Double, triple and then quadruple check your filter value in the config.
