I am upgrading a legacy Grails application and also upgrade the acegi plugin from 0.4 to 0.5.2. When I try to log into the application, I am getting a BadCredentialsException: with “User does not exist”.

The user definitely exists in the database and the credentials are definitely correct. I don’t know much about the acegi plugin but have been reading up and from what I understand there should not have been any upgrade issues. I am also upgrading Grails from 1.0.3 to 1.3.7 at the same time, so that could be related to. Any other ideas?

Thanks.

    BadCredentialsException means the password check failed. Looks like a misconfiguration of the password hashing algorithm – is the algorithm attribute set correctly?

    The default is

    algorithm = 'SHA'

    but it should be overridden in your SecurityConfig.groovy if you use a different approach.

    btw – you should be upgrading to http://grails.org/plugin/spring-security-core 🙂
