If the remote directory in which a user resides is disabled, then the user's username appears on issues and comments instead of the user's display name. This may create significant confusion when trying to search for issues and comments.

Steps to Reproduce

1. Have a remote directory connector with active users.
2. Create an issue and assign it to a user who resides in the remote directory. Example, "Jim Botsfarm". Note that the user's Full Name (display name) is shown in the Assignee field.
3. Delete the user from the remote directory.
4. Disable the remote directory (⚙ > User management > User directories) in which this user resides.

Expected Results

The user's full name (display name) appears in the Assignee field appended with [X]. Example, "Jim Botsfarm [X]".

Actual Results

The user's lowercase username appears in the Assignee field instead. Example, "jbotsfarm".

Notes

This is unexpected because the data in the cwd_user table is not changed. We see deleted_externally set to 1, and the "[X]" we expect is present in the display_name column.

Workaround

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