Enabled users cannot be edited when sharing username with disabled users in separate user directories

Issue Summary

This issue occurs with the following conditions:

• Bitbucket has multiple user directories enabled
• There are separate users in each of those directories that share a username
• The user in the directory of higher order is disabled, and the user in the directory of lower order is enabled

This is reproducible on Data Center: yes

Steps to Reproduce

1. Set up your Bitbucket instance as described above, with two user directories with a shared user. See attached screenshots for an example.
2. Disable the user in one of those directories, and order your user directories so it will be resolved first
3. Go to the Users admin panel. You will see the enabled user and not the disabled one
4. Click on the user

Expected Results

Bitbucket directs you to the edit user page of the enabled user

Actual Results

Bitbucket will show a 404 indicating the selected user does not exist.

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
