Summary
Configuration steps to reuse any previous passwords except last three passwords

Products
eDirectory (NetIQ eDirectory)

Environment
NetIQ eDirectory 9.x

Situation
How to reuse any previous passwords except last three passwords.

Resolution
Go to iManager > Login as admin > Roles and Tasks > Password Policies > Choose the existed password policy > "Universal Password" tab > "Advanced Password Rules" tab > Check "Remove password from history list when the list is full" > Set the number "2" in "History list size"

NOTE: If there is no existing password policy, please create a new password policy.

By setting 2 for "History list size", this will allow us to reuse any previous passwords except last 3 passwords.

When comparing a specified password against previous passwords in the password history, eDirectory differs from Active Directory. If the size of the password history list is “N,” Active Directory compares a specified password against “N” previous passwords. However, eDirectory compares a specified password against “N+1” previous passwords.
