Grouper Developers Forum

From what I can tell so far, the grouper-loader and psp tools are similar in 
that they, move data from one source to another.

The grouper-loader seems to have set of legacy attributes (via the Admin UI) 
and newer attributes (via the Lite UI) that are used to configure 
how/what/where data is pulled from a data source into Grouper.

The psp tool apparently uses a suite of configuration files and a properties 
file to determine how/what/where groups and associated members are 
provisioned to a data repository.

While I’m by no means an expert with using grouper-loader, I understand how 
to use it sufficiently to do what I need it to do.

The psp tool, on the other hand, has configuration files that have a 
complexity for which I do not yet have a sufficient knowledge base, even 
after watching the videos.  

For instance, the tutorials and documentation refer to the fact that the 
Shibboleth libraries (not Shibboleth itself) are used to make the calls to 
ldap to add/del/update data in an LDAP repository.  It would seem that at 
least knowing what those Shibboleth library actions are would help when 
adding configuration to the pap-resolver.xml file.

Here are a couple of the resources I have found that I thought would be 
useful:

When learning the psp tool, what is a good suggested learning track?
