     Done by Vivek


USDU improvements:

if source not reachable it deleted memberships

there was no failsafe on how many it deleted

Shilen adjusted code and created a patch

Tom: what about a stateful approach to removing unresolvable Subjects? Eg, if not resolvable over a long enough period, then automatically remove. Everyone thought this is a *great* idea. :-)

Tom: what about a process for removing stale memberships?

What about memberships going away based on dynamic membership expiration criteria or signal?

Jim: this could be too complex and institution specific to handle within Grouper?

Gail: could it be in a config file  to delete a membership after X days ?

Shilen: some of this can be done through rules

Chris responded to this one


PSP – replace attribute rather than delete + add

may just be a constraint of SPML.

Privilege inheritance that cannot be changed by admins

Shilen: solve by a hook that can be configured?
