Is this the full stacktrace?
On the line of the error we have the following code:

if (identityService.checkPassword(userName, password)) {

So I'm thinking the identityService is null. Did you change something in the configuration or do you see more detailed error messages?

Best regards,

Tijs,

Thanks for the reply. This is the entire stack trace. I carefully checked all the logs after startup and loading the login page. The logs are clean until i attempt to login with a AD user. This is when the above stacktrace appears. I have made two other changes, One was removing the DemoDataGenerator bean as required per the Userguide for ldap integration. Second I configured db.properties file to use a SQL database. These changes and the ones from my first post are the only changes I have made to the activiti since downloading it and deploying it to Tomcat.

Thanks,
Jake

It seems to be an error related to the initialisation of the identity-service. Do you have the required ldap-libraries on your classpath in tomcat?

I'm facing the same issue and, yes, I have the ldap libraries on my classpath. Decompiling DefaultLoginHandler I can see that at line 41 the sentence is:

<code>if(!i$.hasNext())</code>

So the "identityService" is not NULL. The problem should be getting the groups, but I don't know why.

Any help would be apreciated.
