Match cracked password with original username in file

[sqlallstar]

Here is the deal, I am cracking AD passwords and my original file is in this format
username:XXXXX:XXXXXXXXXXXXXX:ZZZZZZZZZZZZZ:::

I crack the passwords

and output to my pot file the format is

ZZZZZZZZZZZZZ:<crackedpassword>

Now what I usually need to do is go back and compare ZZZZZZZZZZZZZ to the ZZZZZZZZZZZZZ in the input file to find the username the password belongs to.

How can I automate this without trying to do it manually?

I attempted to use --show and --username but it just outputs a blank file...

Any help is appreciated.  Otherwise, I can obviously write something in PS or python to match them (even excel) but I am doing something wrong here, obviously.
