PSP Update & Outlook

Dave is working on PSP, including looking at performance issues. Some improvements have been made around change logs.

The group discussed possible approaches for on-going PSP development. Since PSP is based on SPML, optimizations around LDAP operation batching are challenging. Integrating PSP more tightly with Grouper could enable greater optimizations. An advantage to continuing with the PSP's SMPL approach is that it enables the potential to have source and target not related to Grouper. Removing SPML from the PSP would require a re-write. Dave noted that using the Shib Attribute Resolver in the PSP adds overhead. If PSP configuration was not done with the Shib Attribute Resolver, then properties files and the _expression_ language could be used. This would require users to change their current configuration. It was noted that the PSP is currently easy to configure for people who are familiar with Shib and Spring.

Jim stated that the PSP is not fast enough to accommodate the requirements at U. Washington, particularly batching group updates to large group memberships.

The issue is in keeping LDAP up to date with Grouper. Dave noted a more efficient approach could involve queuing events in the PSP using an asynchronous, multi-threaded multi-connection approach. The group will return to considering PSP strategy after Dave has gotten further into it.

Dave is targeting end of July to have some enhancements to the PSP.  We expect to receive more feedback from University of Utah around their experience with the PSP.

Grouper 2.1.4. Release

Chris is finishing work on the Grouper 2.1.4 release. Chris plans to send a note to the core group to do testing.

Dave will continue working in the 2.1 branch of Grouper.

Grouper SCIM Work

Discussions with SURFnet around a Grouper SCIM integration have been going well.

New Grouper UI

https://spaces.internet2.edu/display/Grouper/Grouper+UI+redesign+v2.2

-For the new Grouper UI, Chris is wrapping up the work on user preferences modules, to be used for handling favorites, recently used objects, etc.

-Dojo custom tags will be used to implement combo boxes.  Chris has solves issues around the "throbber" and dependencies on screens.

-Chris plans to put this work into trunk so others can review it.

Legacy Attribute Work 

https://spaces.internet2.edu/display/Grouper/Legacy+attribute+migration

Shilen is making changes in the API related to the Legacy Attribute Migration. After that, Shilen plans to work on hooks and database views.

Shilen has realized that in some cases, the migration could be less smooth than hoped. If a Grouper deployment has privileges with attributes that are based on individuals and not groups, then one result of the migration could be that group admin might no longer have complete access to delegate access to those attributes.

[AI] (Shilen) email users list to ask who is using the legacy attributes and ask how they are using it.

Next Call: Wed. 22-May-2013
