It would be good if there is an option for an admin to select which user directory the new user should be added into on adding new user.
- Adding a new user to INTERNAL (or any non-first) directory is not possible if DELEGATING directory is the first in user directories list.
- Adding a new user to multiple user directories is not possible. Perhaps an admin wanted to have few users added to DELEGATING and INTERNAL directory. Reason could be that when LDAP is down/inaccessible, these users still can login using their INTERNAL passwords.
Confluence Admin can swap the order of User Directories since currently in Confluence, the new user will get created in the first directory with write access rights listed in User Directories.
JIRA has done this well, see
JRA-23933. In JIRA, a dropdown option now will appear once there is an INTERNAL and at least one DELEGATING directory:
