Perform the following steps to change the default icons of social authentication providers:
Go to the socialauth_icons.jsp file located at /opt/novell/nids/lib/webapp/jsp/. You can see all the supported providers and their corresponding public URL locations.
To change the icon of a particular provider, go to the icon variable name of that provider and replace the existing URL location with required URL location.
You can similarly change for other icons defined in the JSP file.
Restart Identity Server after changing the JSP file.
