Please see KerberosDirectoryProvider README for other information with respect to using jaas to implement Kerberos Authentication in Sakai.
In addition, to protect the integrity of your Kerberos password, the use
of a secure Web front-end is HIGHLY recommended. Enabling SSL should be done prior to deploying this code.

Please see KerberosDirectoryProvider README for other information with respect to using jaas to implement Kerberos Authentication in Sakai.
In addition, to protect the integrity of your Kerberos password, the use
of a secure Web front-end is HIGHLY recommended. Enabling SSL should be done prior to deploying this code.
*GENERAL SETUP*
Prerequisite:
-Krb5LoginModule (comes with jdk 1.5)
The package structure for the UCDKerbLDAP.java module is as follows:
edu.ucdavis.security.distauth.sakai2.user
...
//source
...
code
...
edu.ucdavis.security.distauth.sakai2.KerbConf
...
//UCDKrb.properties
...
file
...
that
...
should
...
be
...
copied
...
into
...
Tomcat
...
sakai
...
dir
...
To
...
use
...
this
...
provider:
...
1) Download source from SVN
2) Configure Java for Kerberos using JAAS:
- Create a file jaas.config (jaas.config
...
- example
...
- provided
...
- in
...
- SVN)
...
- in
...
- the
...
- your
...
- Java
...
- installation,
...
- usually
...
- in
...
$JAVA_HOME/lib/security
...
- or
...
- $JAVA_HOME/jre/lib/security.
...
- Add
...
- this

can
...
be

configured
...
by
