1389 - Problem with upper/lower case attribute types

[Leif Hedstrom]

From: Jon Udell <[e-mail]>

Hi Leif,

I've just been poking around in an Exchange Server with PerLDAP. Was
puzzled to see that PrintLDIF was only reporting all lowercase
attributes, not any mixed-case attributes. I haven't figured out why,
but I did notice that although the top level of the $entry structure
exhibited this pathology, its internal _self_obj_ looked OK. So I
changed to

     grep((print "$attr: $_\n"), @{$self->{_self_obj_}->{$attr}});

from

     grep((print "$attr: $_\n"), @{$self->{$attr}});

in ::Entry::PrintLDIF. Which seems to work, but I know there's got to be
more to the story. I'm attaching a Data::Dumper dump of $entry following
a search. As you can see, all non-lowercase attributes at the root level
of $entry are undef. I've only just noticed this because, working with
Netscape Directory Server, I think I've only been seeing lowercase
attributes. Exchange uses mixed-case attributes.

I can't find the place in your Perl code where this is happening, but
it's got to be there. Because in Conn::nextEntry, I can do

        @vals = ldap_get_values_len($self->{"ld"}, $self->{"ldentry"}, $attr);
        print "$attr: $vals[0]\n";

and see all the attributes. So they're coming back OK from the LDAP API
level. I guess one set of attributes mirrors the other, for
change-tracking purposes? I dunno, you sort of lost me with that
multilevel blessed object sleight of hand....

This is, by the way, using the Win32 ActiveState PerlDAP module, if that
matters (it shouldn't, I don't think).

Regards,

More from Jon:

That's good. I have no further info. Where it stands: I'm not sure which of the
two attribute structures is canonical. I am pretty sure that arbitrarily
switching from one to the other, to work around the problem I cited, can't be
the right thing to do.
