I have a large customer that routinely renames AD users and deactivates the account.  Then they use the original name for a new user.  They use a lot of interns and when one intern leaves, their replacement is given the same user name on a new AD account.  Usually, the new user is created within 15 minutes of renaming and disabling the original user.

AD Account "someuser" gets renamed to "someuser-092019DL" (adding 2 digit month, day, and year and the letters DL) and is deactivated (note that they are not removed from any groups).

New AD Account created and named "someuser" and added to the same groups as the previous user.

After this AD account change happens, the LFDS sync is broken until the LF administrator can figure out what user(s) was deactivated and then manually remove the user from LFDS.  Is there anything they can do to help automate this process so that they do not have to continually manually remove users from LFDS?  Below shows the Sync settings.
