Grouper Users - Open Discussion List

[Dave Churchley <>]

Good afternoon

We've been using composite groups for a few years now, mainly using the 
complement operation with exclusion groups. Since the summer, we've also had 
a few intersection groups. 

We've not noticed any problems with group memberships until a couple of weeks 
ago. (That's not to say there definitely weren't any issues, but there 
certainly was not a noticeable impact.) At first it was just with the 
intersection groups but today we've seen it with a complement group, too.

It looks like the composite isn't calculating its membership correctly. 
Editing the composite and resaving it forces it to recalculate the 
membership. We've been using this as a workaround but it's obviously not 
ideal. Some of these composite groups are critical to access control for 
various systems across the University, including physical access into 
buildings.

Is this a known issue? Is there anything we can do about it? We're running 
Grouper v2.2.2. Is there a patch or a better workaround?

Any help would be greatly appreciated as this is a big issue for us at the 
moment.

Thanks in advance.
