I sovled this problem finally!
First I checked tomcat logfile the above 500 error is caused by a
java.lang.IllegalAccessError and found a solution there:
http://osdir.com/ml/java.springframework.user/2008-10/msg00017.html
(simply using spring-ldap-1.2.1.jar instead of spring-ldap-1.2.jar...)
Then when using ldap username/password the page will jump to
roller-ui/login-redirect.rol and display a '500
java.lang.NullPointerException' error -- the same error mentioned by Andreas
Heizenreder's wiki page comment:
https://cwiki.apache.org/confluence/display/ROLLER/Roller+4.0+with+LDAP+and+CAS
Then I added folling code in
roller-weblogger-5.0.3-source\weblogger-web\src\main\java\org\apache\roller\weblogger\ui\core\security\BasicUserAutoProvision.java:
public boolean execute(HttpServletRequest request) {
User ud = CustomUserRegistry.getUserDetailsFromAuthentication(request);
if(ud != null) {
UserManager mgr;
// leo--
ud.setId(org.apache.roller.util.UUIDGenerator.generateUUID());
// --leo
Now rebuild source code to get a new roller-weblogger-web-5.0.3.jar, when a
ldap user logged in the program will create same user in rollerdb
automatically.
(one more thing: the defaultRole for ldap user must be 'editor' instead of
'register', or you will get a '403 Access Denied' error.)
