special characters (@, $, & etc) in the application password causes the client application to not provide admin rights when using SSO

Note: This hasn't been replicated locally by Atlassian yet, but has been raised by multiple customers. If you have hit this issue and can provide steps to reproduce, please add them as a comment on this bug.

When an application is configured in Crowd to with a password that included a non-alphanumeric character, users that should have access to the admin consoles of the client application consoles are denied access.

The Crowd logs contain the following:

2014-09-20 12:55:13,872 http-bio-8095-exec-19 INFO [plugin.rest.filter.BasicApplicationAuthenticationFilter] Invalid authentication for application with name 'conf'

Suspected Steps to Reproduce:

1. Setup Crowd with SSO enabled
2. Setup Confluence (or JIRA etc) to use Crowd (with SSO enabled). Use a special character in the application password.
3. Sign in to Confluence with an admin user and attempt to log into the admin console
   Note: This problem seems to occur after some time. The admin access will work for a while before failing.
