Grouper Users - Open Discussion List

[Chris Hyzer <>]

Can you describe in detail the structure of subjects in the ldap, and send 
the part of the sources.xml for this source (sanitized), and give the 
logs/output when you go to gsh and run:

grouperSession = GrouperSession.startRootSession();

subject = SubjectFinder.findByIdAndSource("theId", "sourceIdFromSources.xml", 
true);

-or-

subject = SubjectFinder.findByIdentifierAndSource("theId", 
"sourceIdFromSources.xml", true);

-or-

subject = SubjectFinder.findByIdOrIdentifierAndSource ("theId", 
"sourceIdFromSources.xml", true);

Thanks,
Chris

Subject: Re: [grouper-users] Provisioning to a different kind of target

I've done some more investigations and grouper is really unable to
resolve subject information contained in my LDAP . I've manually added
a subject in my LDAP that is not also already present in the sample
DB. No matter what I do, grouper just doesn't allow me to manage it.
It's not shown in grouper's ui or anything.

My manually-created LDAP tree matches the one described in grouper's
config file, my manually-created subjects have the correct attributes
and grouper doesn't complain when accessing the LDAP. I'm using
ApacheDS as a directory. Could this be a problem?

I'm a bit confused. What seems to be not working is essentially
loading subjects from a LDAP source. There's nothing fancy here...

Thanks,
--jtellier
