Subject Re: Authentication Practices
Date Fri, 16 May 2003 18:12:20 GMT

BASIC and DIGEST authentication are similar, the difference being that 
DIGEST requires the client to hash a password before sending it. BASIC 
does everything in cleartext. BASIC and DIGEST authenticate against an 
"origin server", and will not solve your multi-server single sign-on 

One solution would be to use a proxy. For example, you could configure 
Apache on the Tomcat box with mod_jk, and use Apache security and the 
Apache Proxy feature to pass requests to the Domino server. In this 
configuration, you would loose access within Tomcat to the servlet 
security APIs (e.g., request.isUserInRole() . . .).
