Synchronization of LDAP groups and organizations

[Clemens Kleibusch]

Hi all,
I have a bunch of JSM projects each belonging to an organization in our company. The users of these organizations are maintained in LDAP and synchronized as "Service Desk Customers" in Jira. I have to manually maintain the organizations in JSM so far. 
Is there any way to automate this? 

Thank you for all suggestions
