I get a Single Sign On Error

In certain cases the user will be presented with a message “Single Sign On Error”. This is because the use either has a
username already and the emails do not match or visa versa. The solution is to completely remove the associated user from
the client site.


Hi, thank you for developing this plugin. But When I Click on single sign On button it shows me error in JSON format {"error":"error","error_description":"temporarily unavailable"} Please Help.
One of SSO's features is that one site logout, other auto logout. How to solve it. e.g. 1 The main site logout, other's site auto logout. 2 The child site logout, other's site auto logout.
