The University implements SSO via the JA-SIG Central Authentication Server (CAS), which is branded as the UH Web Login service. The UH Web Login service has an 8-hour session timeout and also uses session cookies for the ticket granting ticket (TGT) cookie. The 8-hour timeout expires any CAS session that is older than 8 hours. If a session (determined via a user's TGT) is over 8 hours old, the credentials will have to be reentered for access to a SSO resource. The TGT cookie is destroyed when the web browser is closed, thereby ending the CAS session. The next time the person tries to access a SSO resource, CAS will ask again for credentials.
