Documentation
Definition
If a user wants to change his or her password (or is prompted to change his or her password by the system), he or she must enter both the current password and the new password. Having both passwords available as plaintext information allows the system to check the number of characters that are different in the two passwords.
The number of different characters is calculated as follows:
The two character strings are made to overlap as much as possible (by searching for the longest common string and rotating as necessary). The number of different characters (after comparing character-by-character) returns the number the system needs.
Use
Permissible values: 1 - 40
(If the profile parameter login/password_downwards_compatibility has been set to the value 5, the permissible value range is 1 - 8.)
This security policy attribute replaces profile parameter login/min_password_diff.
Dependencies
Example
Old Password "BDAFAG" (6 characters)
New Password "ABC DBA" (7 characters)
Rotated Password "DBAABC " (7 characters)
Number of different characters = 4
