  tracking user activity? (logins) 
 The Question is:
 
Can you please tell me, how can I find out how many times a certain user has
loged in to the system for a range of time?

 The Answer is:
 
  Typical approaches involve the use of accounting data file and/or
  system auditing information, though both approaches depend on the
  settings of accounting and auditing collection having been enabled
  during the specified interval.
 
  The formats of the accounting data file and the audit log are
  documented, as various of the associated utilities and system
  services.
