configuring ldap

slag — Mon, 23 Mar 2015 16:20:39 GMT

I'm trying to connect activiti 5.17.0 to my ldap server.According to the documentation (http://www.activiti.org/userguide/) I need to modify activiti-standalone-context.xml.This file is however not present in after version 5.16.4.I added the following configuration to activiti-custom-context.xml. &

I'll try to reproduce it and see what's happening (with a debugger).

I can confirm this behaviour. Also interested in a solution.

If you are interested i can set log4j on debug mode and post the logs and configuration files.

You need to post the actual errors happening:

23-Mar-2015 12:06:39.964 SEVERE [localhost-startStop-1] org.apache.catalina.core.StandardContext.startInternal Error listenerStart
23-Mar-2015 12:06:39.977 SEVERE [localhost-startStop-1]

The exception stacktraces will be in another log file in tomcat

I tried to reproduce the error by installing from scratch but run into another issue that might explain this problem.

I did a fresh install of both wars.
setup my mysql database connection in rest and explorer.
<code>
db=mysql
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/activiti
jdbc.username=root
jdbc.password=secret
</code>

The demo gets loaded and everything works as expected (didn't test that much).

Then I disabled the demo users (didn't delete anything from the database)
<code>
# demo data properties
create.demo.users=false
create.demo.definitions=false
create.demo.models=false
create.demo.reports=false

# engine properties
engine.schema.update=true
engine.activate.jobexecutor=false
engine.asyncexecutor.enabled=true
engine.asyncexecutor.activate=true
engine.history.level=full
</code>

I get the following error during a restart
<code>

Activiti-explorer is running. When i delete a user from explorer, that user is deleted from the database.
However when i restart tomcat that user is back in the database but his picture_id_ is "NULL".
So it looks like that although the demo is disabled, the user is still being (partly) added and i can login with that "deleted" user.

Is it possible that this error explains the ldap problem?

Re: configuring ldap

jbarrez — Tue, 31 Mar 2015 07:40:33 GMT

The persistent storage exception is ok, that's because we dont do session serialization.

If "create.demo.users=false' is set, it shouldn't create any user. Which user do you see in the database? When using ldap, there shouldn't be anything in the users table.

Re: configuring ldap

slag — Wed, 01 Apr 2015 17:32:06 GMT

My last try to setup activiti i didn't even enable LDAP.
I swichted to Mysql and started tomcat to populate Mysql with testdata.
I stopped tomcat and disabled the demo.
Even with the demo disabled it keeps adding the demo users but with there picture_id_ is set to 'NULL' in the database.
This is a new issue, but might be related to the ldap issues.

Re: configuring ldap

jbarrez — Tue, 07 Apr 2015 12:39:42 GMT

Ok, so I downloaded 5.17, dropped it into a clean Tomcat, changed the properties to mysql. And copied your settings for engine.properties.

But I'm not seeing anything:

mysql> select * from ACT_ID_USER;
Empty set (0.00 sec)

Re: configuring ldap

slag — Fri, 17 Apr 2015 14:44:02 GMT

Ok i got everything working again as normal. the user being created was an error in my configuration.

So back to the original problem. When i add the ldappart to activiti-custom-context.xml activiti crashes.

Crash and exception stacktraces can be found in catalina.out and In localhost.2015-04-17.log

Re: configuring ldap

jbarrez — Tue, 21 Apr 2015 08:22:20 GMT

The exception is

org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [org.activiti.ldap.LDAPConfigurator] for bean with name 'org.activiti.ldap.LDAPConfigurator#de1e852' defined in class path resource [activiti-custom-context.xml]: problem with class file or dependent class; nested exception is java.lang.NoClassDefFoundError: org/activiti/engine/cfg/AbstractProcessEngineConfigurator

Are you mixing jars of Activiti? Seems like some part of your jars are of a later version than others.

Re: configuring ldap

slag — Tue, 21 Apr 2015 14:14:44 GMT

I double checked and i have the correct ldap connector installed.
Since B.Schnarr has the same issue, this also seens unlikely.
Could there be a wrong version on the maven repo?

Re: configuring ldap

jbarrez — Tue, 28 Apr 2015 18:07:56 GMT

I'm not sure if B.Schnarr has the exact same issue. Are you using maven? Can you post your pom.xml?

Re: configuring ldap

slag — Tue, 28 Apr 2015 18:20:37 GMT

I am not compiling or changing code.
I did a fresh install and configured it to use ldap. I manually downloaded the ldap connector from the maven repo and placed it in the lib folder of activiti-explorer.

Re: configuring ldap

jbarrez — Tue, 28 Apr 2015 19:24:32 GMT

Ok last resort then .. can you validate that in the activiti-engine.jar you have a class called AbstractProcessEngineConfigurator.class? If so, I'm officially puzzled by the stacktrace you're getting

Re: configuring ldap

slag — Wed, 29 Apr 2015 08:10:40 GMT

That classfile is in activiti-engine.jar
Is it possible i did something wrong with my configuration?
Would it be possible to update the documentation to reflect change to spring?
Should I restart installation and document my actions step by step so you can reproduce?
If you are interested i can create a Virtualbox machine with my configuration and share it with you.

Re: configuring ldap

jbarrez — Thu, 07 May 2015 12:22:20 GMT

A maven project would be most helpful to get it quickly up and running

Re: configuring ldap

slag — Thu, 07 May 2015 14:27:40 GMT

I don't understand why i should create a maven project and what i would have to do with it.
I copy paste a jar file in an activiti/tomcat folder.
I edit a text file with my ldap config.
I am not compiling 1 letter of code.

Re: configuring ldap

kumarr — Tue, 12 May 2015 17:33:55 GMT

I do have the same problem slag mentioned with 5.17 version of activiti.

When i add the ldappart to activiti-custom-context.xml activiti crashes with the same exact error message as below.
SEVERE: Error listenerStart
May 12, 2015 1:18:00 PM org.apache.catalina.core.StandardContext startInternal
SEVERE: Context [/activiti-explorer] startup failed due to previous errors

Do we go back to a version 5.16 or do we wait for 5.18. Please let us know.
