Description

Currently Bamboo GUI does not allow Admins or Users to rename the username for Bamboo Internal directory users via Edit user interface, see attached

Solution

Provide an option to rename the user similar to changing other details like email, password.

Workaround

The below REST API can be used to rename the users, detail at Bamboo REST API to rename users

curl --user admin_user:admin_password \
  --request PUT \
  --url 'http://localhost:8085/rest/api/latest/admin/users/rename' \
  --header 'Content-Type: application/json' \
  --data '{
  "name": "newusername",
  "oldName": "oldusername"
}'

Please replace admin_user, admin_password with correct values of a user which has admin right on your Bamboo instance.
please replace http://bamboo921:8085 with the URL of your Bamboo instance.
please replace name and oldName with correct values
