Server is not configured for Windows Authentication

Problem

The error message as per the article title appears intermittently for some users on K2 Workspace. This installation was done using SQLUM so the error message does apply to the environment but is still unexpected.

The following error is also found in the host server logs when this happens:

'Error','EnvironmentServer','15100','Generic','SourceCode.Workflow.Runtime.Management [OpenConnection [string[] names]]','15100 Error occurred, ERROR: Server is not configured for Windows Authentication'

Solution

Check the Environment Fields in your Environment Library and make sure that Integrated=False where applicable.

For example, the Category Service field has this original value:Integrated=True;IsPrimaryLogin=True;Authenticate=True;EncryptedPassword=False;Host=K2Server;Port=5555

Since this is a SQLUM installation, the connection string should be updated to show Integrated=False:Integrated=False;IsPrimaryLogin=True;Authenticate=True;EncryptedPassword=False;Host=K2Server;Port=5555
