CMN Exchange to Notes free busy error, "The server has rejected the client credentials." (4345800)

CMN Exchange to Notes free busy error, "The server has rejected the client credentials."

When using Outlook to lookup the free busy data for a Notes user, the free busy query fails. The EWS Web Service shows the following error in the log:

System.ServiceModel.Security.SecurityNegotiationException: The server has rejected the client credentials. ---> System.Security.Authentication.InvalidCredentialException: The server has rejected the client credentials. ---> System.ComponentModel.Win32Exception: The logon attempt failed

In this case the Domino Free Busy Service Endpoint was changed at the bottom of the Web Services settings screen in the CMN Management Console. The CMN Management Consle then updated this configuration change in the EWS web.config file, but not in the DominoFreeBusyService.config file, causing a configuration mismatch.

WORKAROUND

1.) Locate the following file on the CMN Free Busy server:

C:\Program Files (x86)\Dell\Coexistence Manager for Notes\Free Busy Connector\DominoFreeBusyService\DominoFreeBusyService.exe.config

2.) Make a backup copy of the file.

3.) Edit the original file and locate the following settings block:

        <host>
          <baseAddresses>
            <add baseAddress="net.tcp://localhost:8960/FreeBusyService" />
          </baseAddresses>
        </host>

4.) Edit the "baseAddress" to match the string selected in the Domino Free Busy Service Endpoint in the CMN Management Console GUI.

5.) Restart the Domino Free Busy Service.
