Grouper Verified 

 10/2014 (GAP):  GAP is written in perl.   CMU runs three instances of GAP and we configure it differently to provision Grouper groups in 389, AD and isMemberOf attribute in 389.  GAP also supports batching changelog messages to provision large groups. Rahul DoshiCarnegie Mellon University 



The University of Washington's Groups Service sends all group change events to Amazon SNS. An Amazon SQS queue listens on this topic and is read by a .Net program called the UWWI Group Sync Agent. The source code is available under an Apache 2.0 license on BitBucket
