Search filters with wrong case in attribute names lead to wrong result

• Key: DIRSERVER-389
• Type: Bug
• Status: Closed
• Resolution: Fixed
• Priority: Major
• Assignee: Alex Karasulu

Description

Search filters which use attribute names with "wrong" case cause the search operation to return nothing. Example:

$ ldapsearch -D "uid=admin,ou=system" -w ***** -p 10389 -b "dc=apache,dc=org" -s base "(Objectclass=*)"
(nothing)
$

But the following still works as expected:

$ ldapsearch -D "uid=admin,ou=system" -w secret -p 10389 -b "dc=apache,dc=org" -s base "(objectClass=*)"
dc=apache,dc=org
dc=apache
objectClass=extensibleObject
objectClass=domain
objectClass=top

I assume the error is due to changes in class NormalizationService (package org.apache.ldap.server.normalization) done to fix DIREVE-274, because if "wrong" attributes are used, this interceptor raises WARN messages like

[23:37:27] WARN [org.apache.ldap.server.normalization.NormalizationService] - undefined filter based on undefined attributeType 'Objectclass' not evaluated at all. Returning empty enumeration.

which explains the behavior above.

Btw.: The behavior causes Softerra LDAP Administrator 3.2.1 to fail during the exploration of entries. This is how I found it.

I am really sorry about this screw up. It was a bug deep in the BootstrapOidRegistry that caused this. For some reason I think this was the first time we triggered the execution of the code this way. Anyhow its fix and I appologize for any runaround this may have caused you.

I have rebuilt the server and retested this one with a new test case in the test suite here:
http://svn.apache.org/viewcvs.cgi?rev=328604&view=rev
and with Softerra LDAP Administrator (defect was first observed there) as well.
It works as expected now.

I use the Softerra tool, which uses the "(Objectclass=*)" filter for expanding the tree as I learned yesterday, daily with our server. I would have noticed it immediately if the defect has been present before the latest bug fixing changes.

Anyway, thanks for fixing it at once, Alex! Our Softerra users would have hated us for the 0.9.3 release with this defect. It was not possible to browse the directory tree at all.

Now me exploring Apache Directory Server with this GUI client happy again close this issue.
