I have Redhat EL 3,4,5 boxes and need to apply the password policy given below:
-Passwords to be changed at 90 days instead of 180
-Password change to be forced by the system
-Password length must be at least 6 characters long
-Last 3 passwords to be remembered by the system and dont let to be used at the password change
-When 6 continuous wrong login attemp made , the system should block that id
So pratically how can i do this all?
