[activeldap-discuss] <attr> is unknown attribute (ActiveLdap::UnknownAttribute)

[Tim Hermans]

About a year ago we discussed this problem (see thread "unknown objectClass:
what am I doing wrong?").  I'm revisiting it now 'cos I'd really like to see
this work with my LDAP server.

Here's the issue: I get ActiveLdap::UnknownAttribute when I try to find any
attribute.  The search completes properly on the server, ActiveLdap just
doesn't seem to process the results properly.

I believe it might be my proprietary schema.  Here's what a typical tree
item looks like:

DSE root:
              cn=admin root
                                    cn=site
                                               umpn=1.555.5551234
                                               objectclass: top
                                               objectclass: umphone
                                               objectclass: umphonenumber
                                               umivrflow: orion
                                               umivrvariant: testing
                                               umpn: 1.555.5551234
                                               umpnstatus: A
                                               umpntype: P

Here's the code:

require 'active_ldap'

class Target < ActiveLdap::Base
  ldap_mapping :dn_attribute => "umpn",
               :prefix => "",
               :classes => ['top', 'umphone', 'umphonenumber']
end

ActiveLdap::Base.setup_connection :host     => 'ldaphost',
                                  :base     => 'cn=site, cn= admin root',
                                  :bind_dn  => 'cn=root',
                                  :password => 'xxxxxx'

@target = Target.find('1.555.5551234').collect

And the backtrace:

/home/thermans/.gem/gems/activeldap-1.2.1/lib/active_ldap/base.rb:1277:in

    from
/home/thermans/.gem/gems/activeldap-1.2.1/lib/active_ldap/operations.rb:226:in
`find'
    from ldap.rb:17

The schema itself is attached.

The issue seems to be that "real_name" (in "base.rb") does not get set.  I'm
not sure what this is: I don't really have the skills to analyse further.

Can anyone help?

Thanks
