Script Runner -- check if user on JIRA exists in active Directory (LDAP)

[Shreyance Shaw]

We have a requirement to change the assignee of unresolved issues to the project lead if the user is no longer present (quit the firm) on the Active Directory .

Our JIRA is setup for Internal with LDAP Authentication.

The above requirements can be broken into the following parts

1. Get all users from jira-software group  -- Done

2. Find the users within jira-software group have left the firm (not in AD)

3. Find unresolved issues assigned to them and update the assignee to project lead of the project under which the issue resides -- Done

Can someone provide any pointers with #2 ?  

Basically we need to query the LDAP to check for the user.

I see the following class has the methods to do so, but not sure how to get them during runtime

com.atlassian.crowd.directory.DelegatedAuthenticationDirectory

P.S: Able to get the Directory (class Directory) object which has the LDAP URL and other settings but not able to go to the DelegateAuthenticationDirectory from there.

Also, tried to query ldap using groovy-ldap, but after putting the 

groovy-ldap-1.0.2.jar file, into the web-inf/lib folder and restarting JIRA, the script is still not able to resolve the LDAP class file.

Hello! I searched for the user in LDAP through javax.naming. You can find an example here.
