Hello Lavo, We purchased this hook and installed it on our community- http://forum.benchmarksixsigma.com/. New sign up for the community through LinkedIn is working. Manage LinkedIn within the user profile settings is also working. The issue that we are facing is - "If a member with his email id already existing in the community, tries to login through LinkedIn, gets the wrong username and password error." We have currently disabled this hook from our community so that the users do not face any trouble while login. Please help us on this.
