Display reporter department information on the issue screen

[VVC]

Our Jira Data Center is integrated with Microsoft Active Directory using LDAP. We are looking to display the reporter's department information on the issue view screen in Jira Service Management project for a specific issue type.

My preference is ScriptRunner, but it appears the prerequisite is to add a new connection pool inside ScriptRunner Resource by entering the bind account credentials. Is there any other alternative to achieve this?
