Can not log into the WebView after upgrade

Issue/Introduction

After the upgrade of APM to 10.7 GA, we cannot log into the WebView.  we observe the following error messages.

In IntroscopeWebView.log:

[WARN] [com.wily.introscope.webserver] Authentication failed for user <usename>: Error authenticating user <usename> in realm LDAP: Unable to find user "<usename>" because simple bind failed: ldaps-ad.xxxx.xxxx.com:648
[WARN] [org.mortbay.log] AUTH FAILURE: user <usename>

APM environment is integrated with LDAPS.

Environment

Release : 10.7.0

Component : Introscope

Resolution

The cacerts file in APM-Home/jre/lib/security is a completely new file (overwritten by the upgrade/install).  
This caused the loss of the certification chain,  which then caused the LDAP issue. 
Copy certification chain from the backup into the new cacerts file resolved this issue.
