[jBPM Users] - Re: identities from LDAP example pls!
by p4w3l
Thank you very much shiva0. I have managed to test it in my environment. I have modified your code for two important reasons:
- all strings and especially search strings are moved to properties file now. This allows to change search strings for different directories: MS Active Directory , IBM Lotus Domino, etc.
- I have changed the way it search for user groups - it is now looking for members in group record instead of looking for memberOf's in user record. I think it is better attampt and the only possible for IBM Lotus Domino
Below is jbpm.cfg.xml that I am still not sure if it is ok for pluged IdentitySession
| <?xml version="1.0" encoding="UTF-8"?>
| <jbpm-configuration>
| <import resource="jbpm.default.cfg.xml" />
| <import resource="jbpm.tx.hibernate.cfg.xml" />
| <import resource="jbpm.jpdl.cfg.xml" />
| <!-- <import resource="jbpm.identity.cfg.xml" /> -->
| <process-engine-context>
| <identity-service/>
| </process-engine-context>
| <transaction-context>
| <object class="sam.IdentitySessionImpl" />
| </transaction-context>
| </jbpm-configuration>
|
Now the class and then ldap.properties for MS Active Directory and IBM Lotus Domino. I have both of them so parameters are TESTED:
