Grouper Users - Open Discussion List

["Klug, Lawrence" <>]

Hi Tom,

 

Yes, we are trying to determine how UCLA Service Providers could best leverage Grouper.  Will eduMember attributes be sufficiently fine-grained for our applications?  If not, how do we approach implementing Grouper Roles and Permissions?  Our pilot project will most likely be the Content Management System.  We are using a Zope-based product called “Plone.”  What are the steps for moving Plone Roles and Permissions management into Grouper?   LDAP delivery via Shibboleth is an elegant solution, but Roles and Permissions may require another strategy.  Thinking this through now could prevent future pain.

 

Thanks,

 

Lawrence

Lawrence,

Glad to hear that you guys are thinking this through so thoroughly. You raise a hard question, especially when considered abstractly, about how to represent roles & permissions in an LDAP directory. Since AFAIK all OTS apps that get permission-related info from LDAP only rely on user attributes and group memberships (maybe with proprietary objectclasses), is your question more specifically aimed at how UCLA-grown apps should get role & perm info from grouper? Is it particularly desirable that that happen via LDAP?

Hi Chris,

 

We are defining our long-term access management strategy with Grouper.  We have tested “eduMember” for transmitting membership info through Shibboleth.   Roles and Permissions are internal Grouper attributes that would not live in the Enterprise Directory(?)   Trying to focus on exactly how Roles and Permissions attributes can be consumed by a University Web application now and in the future.

 

Thanks,

 

Lawrence

We have two examples where we sync all the permissions to the application since it does DB joins on the assignments, or we dont want grouper as a performance bottleneck or a runtime dependency.  The change log consumer and grouper client handle real time updates (tells it to do a full resync)

We created a simple demo app to consume isMemberOf attribute via Shibboleth and make a few simple Web Service calls.  It works fine.  What if we want to use Role and Permission attributes?  How would they be transmitted to the Client application?  Could they be released as Shibboleth attributes or direct Web Service call?   What are other universities doing?

 

Thanks,
