Compound query question - organization with cn vs. o?

["Matthew M. DeLoera" <mdeloera@exacq.com>]

Hello,

Apologies if this isn't the appropriate list. Searched archives but didn't manage to find anything that seemed related…

This query does not return any results:

(|(&(objectClass=groupOfNames)(cn=Domain Users))(&(objectClass=inetorgperson)(cn=Domain Users))(&(objectClass=organization)(o=Domain Users)))

But, this query does:

(|(&(objectClass=groupOfNames)(cn=Domain Users))(&(objectClass=inetorgperson)(cn=Domain Users))(&(objectClass=organization)(cn=Domain Users)))

Since RFC 2256 defines organization as STRUCTURAL, with o as MUST, and does not associate cn at all, I'm stumped.

FYI, there exists a groupOfNames object with cn=Domain Users.

I guess, why would my organization (3rd) clause matter at all? Since the groupOfNames object satisfies the groupOfNames (1st) clause, I was expecting it to be returned regardless of whether the subsequent 2 clauses match anything.

And out of curiosity, this query fails:

(|(&(objectClass=groupOfNames)(cn=Domain Users))(&(objectClass=inetorgperson)(o=Domain Users))(&(objectClass=organization)(cn=Domain Users)))

My guess is that if a subsequent clause specifies an attribute that's not defined for an objectClass, the query fails even if the first clause is known to be good? If that's how things work, I can deal with that. But I just can't find any documentation that clarifies this (or I'm totally missing something super obvious!).

Can anyone explain this to me, or point me to some docs that I should go read? Is there a missing piece of info that I should mention? Any suggestions would be really, really appreciated!

Regards,
- Matthew
