Setting the assigned user based on the user property

[Phillip Campbell]

I have some integrations with built using Scriptrunner and some other JIRA tools. I currently have a external tool creating new issues and then storing JSON key/values using issue properties. 

One of the key/value pairs I return is the samAccount from my Active directory. This is because the systems I am integrating with JIRA authenticate in different ways.

What I want to do is:

• Create a new JIRA issue using the REST API (I can do this already)
• Set/Update the issue.properties to include all of the external system key/value pairs including the samAccount key/value  (I can do this already)
• Find the JIRA user with the user property that equals the samAccount key/value (This part does not work)
• Update the assignee based on the user found (I have not got to this part yet)

Any suggestions would help.
