Report to determine if users are sharing password

Question

We would like to determine if users are sharing password, is there any
report that can show this kind of data?
We would like to compare the terminal ID with username in order to
indentify anyone is sharing password. However, Table USR41 only shows
the current active users with terminal ID who logged on to the system
not the historical data. We notice that t-code stat can show the
historical terminal ID but is extracted from a structure not table. We
have our in house programmer who can develop such program but we would
like to know how the (STAT) structure extracts the terminal ID data
from? which table?

Answer 1

Hi,
Table USR41 is a dynamic table and keeps on chaging as users are logged in and logged off. You can write an program on the table and fetch the dummy logins and log off the duplicate users by calling the function module (for logging off user).
Other option
You can also use tcode SM04 for logging off the duplicate users.
AL08 can also be used to fetch the duplicate logons both these tcodes fetch the table USR41.
