Downloaded the trial and started testing a bit. Redirect works fine if a user is direct member of an AD group.
However I'm unable to get it to work with nested groups. IE my domainuser is member of "Group Level 2". Group Level 2 is member of Group Level 1. The Redirect rule is applied to Group Level 1.
Can you please confirm if this should be working or not?
Unfortunately at this time, Bamboo Group Redirect Web Part does not support to work with nested groups. I have added this request to the product's enhancement list for consideration in a future release. You could use "Add more groups" function to connect groups.
If you have any questions, please let us know.
