Subject [jira] [Commented] (DIRSTUDIO-913) Removing elements with children under "ou=schema" (ApacheDS) does lead to LDAP errors
Date Thu, 01 May 2014 19:59:16 GMT

    [ https://issues.apache.org/jira/browse/DIRSTUDIO-913?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13986929#comment-13986929

Emmanuel Lecharny commented on DIRSTUDIO-913:
---------------------------------------------

Stefan, your analysis is correct.
We have added a flag in the Schema Manager that allows someone to modify the schema (add or
delete elements) without doing any check (ie, you may be in an inconsistent state at some
point), and a method that does a check at the end. This is what we call the 'relaxed' schema.

We could leverage this feature, but that would require to send a control to tell the server
to switch to a releaxed mode, and another control to tell the server to switch back to a checked
schema (and validate or invalidate the modifications).

This is quite a bit of work, but it's feasible. I don't think we need t for the current version
of the server...
