SharePoint Single Signon Error 0x8063064a


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 0x8063064a. 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.
