I'm able to add users to SharePoint 2013 but not the groups. This is a security group.. the same group we are using for sp 2010. issue is only with my new server farm 2013.. even people picker able to recognize the group name and not displaying when I try to open that group.. the error I'm getting is something went wrong.
Please Help me to overcome from this Issue..
Thanks & Regards, Anudeep
