Grouper Users - Open Discussion List

[Michael R Gettes <>]

Yep, I saw this too.  There also doesn’t seem to be an indicator in the log 
of start and stop of the fullsync (yes, you can consult the 
grouper_loader_log as well).  I thought leaving the error there for now cuz 
it easily shows when the fullsync is finished :-)  While this is humorous to 
me, for now, the error is useful.
