Auditing - is there a way to track adding and removing users

davmac1

Is there a way to track adding and removing users to Navision. This is for Navision 2.6 MS SQL Server option. (We need it to meet a Sarbanes-Oxley requirement.)
All the users are via Windows login.
The Windows Login table in SQL Server does not show the user name, just a character version of the SID.

The only way I can see to do it is to add code to the table in Navision to write entries to a new table of new users, changed users, and deleted users.

Is there any better way or something laready available?
