Some good threads
How do I configure Tomcat to use SSL?
Try these instructions.
How do I use a self-signed certificate?
A: Trusting the Self-Signed Certificate
DummyTrustManager for development
Joakim Recht suggested on the CAS list that in development you can avoid the need to install your self-signed CAS server certificate on your CAS clients (and your CAS client certificate on your CAS server when the clients need to be securely accessed for CAS to give them Proxy Tickets) by using the DummyTrustManager from here .
This accepts all certificates, including self-signed.
This would be neither secure nor appropriate in production, but it may be just the thing to get off the ground in development.
To use the DummyTrustManager, put the files DummySSLSocketFactory.java and DummyTrustManager.java into src/edu/yale/its/tp/cas/util and add
((HttpsURLConnection)uc).setSSLSocketFactory(new DummySSLSocketFactory());
to SecureURL.java just after
URLConnection uc = u.openConnection();
Where can I learn more about the keytool?
At the keytool page.
Thanks to Joakim Rect for originally suggesting DummyTrustManager on the CAS list.
