Clicking on any login link (including the one at www.jboss.org) takes you to the new SSO login page. From here you're automatically logged into all of the above applications when you visit them without need to login again. An SSO session created using the "Remember Me" feature from the SSO login page is valid for 10 days for security reasons. After 10 days you'll be forced to login again.
Logout links log you out from the individual applications and you're then given the option to perform an SSO logout from the relevant log out page. The only exception to this is the logout link on www.jboss.org which performs an SSO logout directly (again because you're not 'logging out' from www.jboss.org).
As part of this release we also updated the SBS user interface to have a new fluid design which gives the content more room to breath (no fixed width anymore).
The Website FAQ  and help pages  have been updated to include information about SSO.
If you experience problems logging in using the new SSO login page please try the 'I forgot my password' link which may help sort things out in the background (syncing passwords across systems for example). For problems in general please use the 'sso.jboss.org' component of our ORG JIRA project:
