Tomcat User Authentication

[Kevin Mullin <mu...@us.ibm.com>]

Tomcat comes with a file, tomcat-users.xml, which is used for user 
authentication and to determine what they can access.  We have our own 
userid authentication process on our IBM mainframe computers which uses 
something called RACF.  Is there a way to get Tomcat to use this processs 
to determine proper userid and password authentication, in addition to 
using its own tomcat-users.xml to determine what the individual is capable 
of doing?

You probably don't want to use tomcat-users.xml at all; replace it
completely with a JAAS-compliant interface to RACF.  Take a look at:
http://tomcat.apache.org/tomcat-5.5-doc/realm-howto.html

Pay special attention to the JAAS Realm section, and study the JAAS
documention on the Sun web site.  We did it for our mainframes, using
both our traditional security and our native Kerberos mechanisms.  And
no, we won't send you the code.
