>Description:
When a user account is modified to change the UID, files and directories created by the prior UID still show as owned by that username. However, the user cannot access them since they are (presumably) actually owned by the prior UID. Other OS's I've used deal with this case by displaying the files as owned by the prior UID number, so they can be readily identified and updated.
>How-To-Repeat:
Create a user. Create files as that user (permissions 600). ls -l the files and verify that they are owned by that username. Change the user's UID (as root, using pw). ls -l the files and verify that they are still shown as owned by the username. Attempt to access the files and verify that the new UID cannot access them.
>Fix:
The file ownerships can be updated normally using chown. Of course, it's confusing, since both old UID and new UID files for a given user show as being owned by <username>. I don't know of a workaround.
