Documentation for Crowd 2.2. Documentation for other versions of Crowd is available too.
Logging out of Crowd is easy — just click the 'Log Out' link at the top of the Crowd screen.
If your administrator has configured Crowd to allow single sign-on (SSO), then you will be automatically logged out of all Crowd-connected applications when you log out of Crowd.
This automatic logout will also happen if you log out of one of the other Crowd-connected applications — you will be logged out of Crowd and the other application(s) at the same time.
