No applications I'm aware of natively integrate directly with grouper or signet, ie, they don't access the grouper or signet APIs.

The LDAP Provisioning Connector (Ldappc) provides a way to "publish" grouper groups and signet permissions to an LDAP directory. Many applications natively use group information in an LDAP directory. None directly use signet permissions - that art is too new.

People from some of the universities using or considering grouper post messages to this list (archives are available at <>).

To my knowledge, the University of Chicago is the only university currently engaged with implementing signet, though Cornell has also looked pretty deeply into it. However, Stanford and University of Washington have been operating privilege management systems like signet for several years, and MIT's Roles Database, which has been around for quite some time, is arguably comparable.

There is also some investigation, transcending individual campuses, of using grouper and/or signet as a basis for managing common resources shared among many collaborative activities. The Cancer BioInformatics Grid (caBIG) uses "grid grouper" (grouper API exposed as a grid service) to manage access to grid resources distributed among 60 or so national cancer research centers in the US. And several efforts have been talking about or prototyping collaboration platforms or VO management platforms that incorporate group and privilege management.

Thanks for your answers. We want to integrate Grouper and Signet with ours various application (Sakai, SAP, uPortal) just not PHP applicaiton. What kind of application integrate with Grouper and Signate, is there any list of them?
Otherwise, Which University use Grouper and Signate? Is there any address to contain University list? We could not found any list on the web. Meanwhile my English isn't very well, sorry.

Thanks again.
