Add additional configuration options to the documentation and/or test for null?

[B5A7]

Trying to use the plugin, I get this error:
Cannot convert value of type [groovy.util.ConfigObject] to required type [java.lang.String]

Caused by endpointUrl = conf.springsecurity.invalidate.endpointUrl in SecurityStatelessGrailsPlugin?

http://stackoverflow.com/questions/21125979/grails-events-push-plugin-problems-with-grails-2-3-3 may be related.

Adding this items to Config.groovy solves the error:
grails.plugin.security.stateless.springsecurity.invalidate.endpointUrl = "xxxx"

Could also include
grails.plugin.security.stateless.springsecurity.invalidate.active = true/false

The discussion about salting in http://www.kaleidos.net/blog/295/stateless-authentication-with-api-rest/ is probably relevant - I am guessing that is what the invalidate call should do - clear the salt?

My configuration:
grails 2.4.4
compile ':security-stateless:0.0.7'
compile ":spring-security-core:2.0-RC4"
compile ":spring-security-ldap:2.0-RC2"
compile ":spring-security-ui:1.0-RC2"
