Signon Password Case
This profile option is not available from the beginning.
With 11i.ATG_PF.H RUP3  comes the system profile 'Password Case Option'
After 11i.ATG_PF.H.RUP4  this system profile option was renamed to  'Signon Password Case'.
There are two settings: 'Sensitive' and 'Insensitive'.
The default is 'Insensitive'.
Setting this profile option to 'Sensitive' will make the password case sensitive.
'Mixed' is no longer supported.

These profiles should only be set at Site level.
They can be set at other levels, such as User or Responsibility.

However, when logging in there is no User context, so if a User is prompted to
change their password at login, the profiles are only evaluated at site level.

Once logged in and resetting passwords using Preferences->Change Password,
or the Security ->User->Define form these other levels will have effect and will confuse the issue.

So these profiles should only be set at Site level, for consistent enforcement.

In the Define User screen we can set the Password Expiration to either
• Days (see example),
• Accesses (the number of logins) or
• None.

Combining the profile options with the Password Expiration will give you a robust password policy for Oracle E-Business Suite.
