LDAP attributes do not exist when they have no value?

I'm coding against LDAP on eDir 8.7.  I noticed that when I searched for a
particular user object (for example) and tried to retrieve the givenName
attribute (for example), that if the user's givenName was set to blank/empty
or never populated at all, that the givenName attribute would not even
exist.  When I populate the givenName (via NWAdmin or any tool), the
givenName attribute appears and I can query it via LDAP.  If I reset the
givenName to a blank, it once again disappears.  I have confirmed this using
a tool which does a raw dump of all the LDAP attributes of an object.

Thoughts?
Thanks,
Matt

This is normal, it's the way LDAP works.

Ah, I didn't know if that was part of the spec.  Interesting...

However, when I do a dsbrowse -a, the attributes don't show there either
(when they're not populated), so this doesn't seem consistent, since that is
working directly against the database.

Thoughts?

That's correct. If there's no value, the attribute doesn't exist.

Apparently though that's not an LDAP thing, it's either an eDir thing or
some other underlying standard.

It's not limited to LDAP, no. Most directory services work this way. But 
NLDAP conforms to the LDAP specs here, eDir just happens to do the same 
thing. :)

Using specific values from multi-valued attributes via LDAP?
I understand how to inject LDAP attribute data in to the authentication process via the form fill, but is there a way to select a specific value from a multivalued attribute? Say for example that I have an attribute called "myPasswords" that has multiple string values specifying a URL and a stored password. I'd need to be able to search for the value needed for the URL I'm authenticating to, then parse out the password section of that string and inject it in to the "password" box in the form. Possible?

LDAP Attribute Values
Hi everyone,Is it possible to have dynamic/virtual attribute values for the LDAP owner attribute.  For example, if I have an owner attribute value set for an OU (organizational unit), can all users in that OU have that same owner attribute value dynamically assigned to them?Thanks. I am not sure what you mean.  Are you asking is there an AD supported way to infer that objects in an OU belong to the same owner of the OU?  Not really is the answer.  There are things like security ownership and things like 'managedBy' attribute that can show the 'owner' of an...

One attribute value to two attributes/ values in eDir
Collective, I have a very interesting issue. I have the need to break one attribute that is in AD (ADval1) to two attributes in eDir (attrval1 and attrval2) .

The attribute in AD looks like this: AD attribute value data 1 | value data 2 In eDir it looks like this: eDir attribute 1 vlaue data 1 eDir attribute 2 value data 2 I don't know if that's clear, when it was explained to me it was a white board.

eDirectory --> LDAP values
Hi. We're using SLES10, OES2 for the majority of our network. For a 3rd-party application (Request Tracker, aka RT), I want to use LDAP authentication. Not a problem. However, I swear that the eDir values exposed in LDAP have changed. In our original implementation 4 years ago, I could request fullName with an ldapsearch and get the user's full name. But not now. The question is: how can I get the users' full names out of eDir so that they are accessible via LDAP? -- mpjames ------------------------------------------------------------------------ the pr...

Hide eDirectory attributes from LDAP
I've got a customer with an interesting question; I've not played deeply enough with LDAP to provide him with an answer.

So...is there a way to NOT expose a field in LDAP? Thanks!
