In my case, this error occurred when I was recovering an old BizTalk Server 2004 development environment:
“The master secret has not been backed up. If you lose the master secret all the information stored in the SSO system will be lost permanently and your systems may fail to work correctly. Please use the SSO admin tools to back up your master secret.”
And this is actually a well-known error, and this can occur in all versions of BizTalk Server, not only in the 2004 version, and it is also very easy to solve.
📝 One-Minute Brief
If your Event Viewer is flooded with ENTSSO Event ID 10589, it means your Master Secret hasn’t been backed up. This isn’t just a warning; it’s a critical risk. If your SSO server fails and you don’t have this backup, you lose access to all encrypted BizTalk data permanently. The fix is a simple command-line execution (ssoconfig -backupsecret) or a few clicks in the SSO Administration console. Do it now to ensure your environment is disaster-recovery ready.
Cause
The reason for this error is that the master secret has not yet been backed up. And you need to be very careful because if you lose the master secret, all the information stored in the SSO system will be lost permanently, and your systems may fail to work correctly.
Solution
As I mentioned earlier, this error is extremely easy to solve, and for this, we only need to:
- On the Start menu, click Run and type cmd to open the Command Prompt.
- At the Command Prompt window, go to the Enterprise Single Sign-On installation directory.
- The default installation directory is C:\Program Files\Common Files\Enterprise Single Sign-On.
- And type the following command to back up your master secret key:
- ssoconfig -backupsecret <full path to the backup file>
- This command will ask you to provide a password and a reminder, as you can see in the picture below:
After that, your master secret will be backed up, and the error will be solved.
