By default, the Service Account's user name and password are entered in Hyland.Core.FullText.NTService.exe.config in clear text. Although these credentials cannot be used to log on to any OnBase client application, it is considered a security best practice to encrypt them in the Windows registry using the aspnet_setreg utility. The Full Text Service can then be configured to refer to the encrypted registry keys to retrieve the Service Account's user name and password.
