Question Regarding LDAP UserCallBack Implementation

[roxy1987]

Hi,

With the default implementation of UserCallBack, I believe, jBPM checks the table ORGANIZATIONALENTITY to see if the user is valid or not.

Now if I implement callBack with LDAP server, do I need to worry about putting the user information in the table ORGANIZATIONALENTITY??

I am concerned that if I use LDAP directly, and if I leave the table empty, there may be some feature/API which look for user information in the database.

Regards.

Hi !

This is my turn to reply to you.

I have implemented my own userGroupCallBack with ldap. And for this part it works more or less. When it checks a user existence, it automatically added him (or the group) in the database.

But, when the user already exists in the database it still tries to insert it and rise a MySQL duplicate primary key error. But this error desn't lock the process.

So you don't need to load users and groups in the table.

Thanks Sandra.

I can handle the exception as long as it is not getting in the way of the process. WIll it be okay for you to share your call back class with me?

I'm sorry but my userGroupCallbackImpl won't be very usefull for you because I use a common lib to access the ldap server in my job. So this is not the example you need.

But Mauricio Salatino has made a good example linked to his book :

https://github.com/Salaboy/jBPM5-Developer-Guide/blob/master/chapter_07/jBPM5-HumanTaskAndProcesses/src/test/resources/jbpm.usergroup.callback.properties

and java code :

Hope this will help you.
