AD Old Password Still Accepted

Products

• CA Single Sign On Secure Proxy Server (SiteMinder)
• CA Single Sign On SOA Security Manager (SiteMinder)
• CA Single Sign-On

Issue/Introduction

We have recently implemented a change password mechanism using smpwservices.fcc for a new application. It is working as expected and if I logoff and logon with new credentials everything seem to work fine.

The problem is that (for a certain period of time) I'm able to login with old credentials too. Why is this possible? Is it a caching issue? How can I force Siteminder to accept only the new credentials?

Environment

Release:
Component: SMPLC

Cause

This is expected as AD will keep old password valid for some time:

Resolution

Product is working as designed.

Delay is in 'new password' propagation in AD infrastructure
