As i already wrote to somebody else, i'm not maintaining this plugin anymore. Dealing with acegi-security is waste of time in 2018 year.
Also please remove me from jira assigns.
Huge refactoring to the right acegi/jenkins api consumption is still available in branch (remember me works for non SSO configuration, SSO needs fix/change in one place). If you want to have correct plugin implementation you can end refactored and cleaned code.
