Subject [jira] Updated: (DIRSERVER-824) Collective attributes are not evaluated in search operations when they are used in filter expressions
Date Fri, 23 Feb 2007 20:06:05 GMT

     [ https://issues.apache.org/jira/browse/DIRSERVER-824?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Alex Karasulu updated DIRSERVER-824:
------------------------------------

    Fix Version/s:     (was: 1.5.0)
                   1.5.1

Emmanuel you're right this is a tough problem to solve efficiently.  I'll put this one off
until after 1.5.0.  

Incidentally one way to implement this would be to give search some extra attributes to consider
while attempting to match for the filter.  These additional attributes can be merged into
the entry used for evaluation.  This away any attribute can be injected into an entry to effect
evaluation regardless of the partition implementation.  

Actually with this mechanism we can support several virtual/dynamic attributes.  What do you
think about this idea?

> As collective attributes never hit the database, they are not evaluated upon search operations
if they are used in filters. This is an hard issue to fix but we may also support this kind
of virtual attributes in the future, so we need a way to handle such cases. One solution can
be injecting the collective attributes into entries before search operations. Other LDAP servers
may be doing this. (I had felt this when I read their documents.) Hoever I am not sure about
the negative effects of that way on performance.
