Adfind and a batch file would do it.
As an example we had a load of old NT4 SIDs we wanted to look up against SID history in AD to see what the new AD group was.
just had a list of SIDs in a text file, in your case this would be the users names.
and then...
for /f "delims=" %%A in (%1) do adfind -b "OU=???,DC=???,DC=???,DC=???" -s subtree -f "&(sidhistory=%%A)" cn sidhistory -adcsv | find "," >> %1.sidh2cn.%DATE:/=-%.txt
so for yours, you'd need to change
(sidhistory=%%A)
to search against the users full name, and then the bits after that...
cn sidhistory
are the values you want returned. the
-adcsv
tells it to output the results as csv and then the
>> %1.sidh2cn.%DATE:/=-%.txt
is the results file you are piping out to.
