What is the minimum length of a JIRA Core (server) username

Thomas Øhrbom May 18, 2017

Our new instance of JIRA Core (server) is connected to Active Directory (AD). Most of our users have usernames that are just 2 characters long (example: lk). When testing for a few users, I find that the users with a 2 character username cannot log in, while users with longer usernames have no problem.

Is there a minimum length of usernames defined somewhere? I can find no documentation on this.

If there is a limit, can this be changed somehow?

Hi @Thomas Øhrbom 

Sorry for the late response.

As far as I know, Jira Core does not have a minimum username length requirement, but the Active Directory (AD) configuration might have a minimum username length policy in place.
