Microsoft Online Sign In Client Configuration

The Microsoft Online Sign In Client uses a local machine configuration file, which contains:

• Online Service Sign Sign-On Webservice End Point connection settings
• Connection timeout value setting
• Proxy Authentication setting

All of these configuration settings can be found in the following location (default):

• C:\Program Files\Microsoft Online\Sign In\SignIn.exe.config

The above Bolded items are of particular interest as they control connectivity with the Microsoft Online Hosted Services Sign In Web Services:

• Binding - UID
  • sendTimeout="00:01:00" - Controls how long the client will wait for a response from the Online Sign In Service before timing out.  You can extend this setting if you are connecting over a WAN connection or have a very slow connection, which requires additional time to complete transactions such as this.
  • bypassProxyOnLocal="false" - Controls whether the client should not use a Proxy Server for local connections.  However the Online Hosted Services will ALWAYS be remote, so this setting is not used at this time.
  • useDefaultWebProxy="true" - Controls how the Sign In Client uses your browsers Internet Explorer (i.e. Internet Explorer --> Internet Options --> Connections --> LAN Settings).
• Binding - wsHttpBinding
  • https://signinservice.microsoftonline.com/ssoservice" - Controls the Online Hosted Sign In Webservices end-point. 
    • Note:   This should never be modified, as it is the central Sign In Services location for the Online space.
