Script error on Python3 in RHEL 8

[harrydevine]

I am using this script in our Ansible Tower server. It works great on RHEL 7 with Python 2.7, but on a new Tower installation on RHEL 8 and Python 3, we get the following error. Red Hat support via ticket #02770664 requested that I reach out to the script author.

Thanks, Harry

The version of the script in this repository isn't Python 3 compatible. Red Hat Training uses a forked version that they've migrated to Python 3, I'll talk to them about possible updates.

Fix for except ldap.LDAPError, e: ^ SyntaxError: invalid is in PR #7, haven't had a chance to test it yet.

I copied the updated python script to my RHEL 8 Ansible Tower, sync'ed the Inventory Script, and it succeeded. I see my IDM groups and hosts, so it looks like its working. I really appreciate your time on this!

Glad to hear it's working! Merging and closing.
