We need to import users (app 200 users at least) and we have found Jelly scripts 
https://confluence.atlassian.com/display/JIRA/Jelly+Tags#JellyTags-jira:CreateUser
But there is no choice to set what "kind of " user, so I am thinking if it is possible to use this and get that type of account. With the LDAP Authentication that is.
<span><JiraJelly xmlns:jira=</span><span>"jelly:com.atlassian.jira.jelly.JiraTagLib"</span><span>></span>
<span><jira:CreateUser username=</span><span>"new-user"</span><span>password=</span><span>"password"</span><span>confirm=</span><span>"password"</span>
<span> </span><span>fullname=</span><span>"Full name"</span><span>email=</span><span>"<a href="mailto:test@test.com" rel="nofollow noopener noreferrer">test@test.com</a>"</span><span>/></span>
<span><jira:CreateUser username=</span><span>"new-user"</span><span> password=</span><span>"password"</span><span> confirm=</span><span>"password"</span>
<span> fullname=</span><span>"Full name"</span><span> email=</span><span>"<a href="mailto:test@test.com" rel="nofollow noopener noreferrer">test@test.com</a>"</span><span>/></span>
<span></JiraJelly></span>
Perhaps thera are other ways to do this? I would be greatful to get input here.
