TypeError: can't convert nil into Array when searching for groups

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Search for groups where one attributes returns nil (why ? I don't know) 

u=AD::User.find("cpennafo")
p u.groupes.collect{|g|g.cn}

What is the expected output? What do you see instead?

The expected output is : 

["PEMOD-CRIH", "CANADA-CRIH" ...] # A list of groups cn

The result I see instead is : 

TypeError: can't convert nil into Array
    from /Library/Ruby/Gems/1.8/gems/activeldap-1.2.1/lib/active_ldap/operations.rb:71:in 
`concat'
    from /Library/Ruby/Gems/1.8/gems/activeldap-1.2.1/lib/active_ldap/operations.rb:71:in 
`search'

What version of the product are you using? On what operating system?
activeldap-1.2.1

Please provide any additional information below.

I patched activeldap-1.2.1/lib/active_ldap/operations.rb on line 71 
transforming 
normalized_value into a table. It also seems to work adding a "if 
normalized_value" at the end of 
the line :
 71             attributes[normalized_attr].concat([normalized_value])

Could you show your AD::User class definition and all backtrace on error?

Looks like I'm having the exact same issue here.

               :prefix => "ou=wiu",
               :classes => ['top','person','organizationalPerson','user'],
               :scope => :sub

'distinguishedName'

Adding "if normalized_value" to the end of line 71 in operations.rb seems to 
resolve
the issue for me too.  Not sure if this will break anything else though.

Thanks.
We need data returned by LDAP server.

Please modify
/opt/local/lib/ruby/gems/1.8/gems/activeldap-1.2.1/lib/active_ldap/operations.rb
 like
the following:

  65      values = options[:connection].search(search_options) do |dn, attrs|
  ADD!!!    p [dn, attrs]
  66        attributes = {}
  67        attrs.each do |key, _value|
  68          normalized_attr, normalized_value =
  69            normalize_attribute_options(key, _value)
  70          attributes[normalized_attr] ||= []
  71          attributes[normalized_attr].concat(normalized_value)
  72        end
  73        [dn, attributes]
  74      end

And run your script again.

Please show the output of your script.
