Grails Spring Security Plugin Migrate User Passwords from 1.2.7.3 to 2.0
I am using Grails 2.3.2 and am trying to upgrade my Spring Security Core Plugin from 1.2.7.3 to 2.0. I made all the import changes and got my app to start, but I was unable to login. One of the changes in 2.0 is that it uses the bcrypt algorithm for passwords, making all my old passwords useless. So, I went through the password reset process in my app and sure enough after that I could log in just fine. But, I want to keep my old passwords for all my users, so I went and found the documentation for the 1.2.7.3 version of the plugin and looked up what algorithm it used: http://grails-plugins
