UID for SMB Guest account conflicts with another user
If the UID for the Guest account conflicts with another user, you can delete the Guest account and
recreate it with another UID.
Use the following command to delete the Guest account, and enter yes when you are prompted
to confirm the operation:
/opt/likewise/bin/lw-del-user Guest
Recreate the Guest account, specifying a new UID:
/opt/likewise/bin/lw-add-user --force --uid Guest
To have the system generate the UID, omit the --uid option.
