Our environment had 2 front end servers with MOSS 2007. The single sign-on service was leveraged within the web parts and everything worked fine on one server. However the following message was found in the event log on the second front-end server.
Event Type: Error
Event Source: Office SharePoint Server
Event Category: SSO
Event ID: 6494
Date: 7/1/2008
Time: 2:43:21 PM
User: N/A
Description:
The Microsoft Single Sign-on (SSOSrv) service failed to store credentials for user <DOMAIN\UserName>, enterprise application definition postini. The error returned was 0×8063064a. For more information, see the Microsoft SharePoint Products and Technologies Software Development Kit (SDK).
Resolution:
The Microsoft Single Sign-On Service was running as “LocalSystem” on the second server. Once we changed that to run as the MOSS 2007 application pool account, everything started working back as usual.
