A feature enhancement to the schema conversion tool?  I'm not sure who
maintains that now.

well, I was simply running the schema-reload.pl script; the script ran fine, it was internal dynamic reload task on the directory server that had a problem, per the error log for the slapd instance:

[31/Aug/2010:15:30:23 -0700] schemareload - Schema reload task starts (schema dir: default) ...

So the problem is that SYNTAX is not inherited from the parent?
What version of 389-ds-base are you using?
Can you post the definitions of the parent and child attributes?

 

Yeah, I messed with it a bit not knowing what it was talking about; at first I tried to figure out why it was loading my 97hosting.ldif file earlier than the 00core.ldif file that had the syntax that was "missing," since that seemed to be what the error was saying.

As a simple example though, if I try to create an attribute with "SUP top" it fails; I can do that with an objectclass with no problems, but not with an attributetype.  Here's an extremely over-simplified example:

You can't have an attribute use an objectclass as it's superior.  An attribute can only use another attribute as it's superior.  The same restriction goes for an objectclass.  An objectclass can only use another objectclass as it's superior.

Doing the same with an objectclass ("SUP top") works fine, obviously.  All this means is I can't define attributes that are inheritance types; no matter how many times I may repeat the same three lines in many entries, they have to be repeated; I can't just say "SUP nocastr128" instead.

Again, doesn't stop anything from working, I just did a global search/replace in vi and was done quickly.  It just looks messier, and was curious why it wasn't allowed to have superior attributes, or if there was something I was doing wrong?
