Increasing the allowable time difference between client and server

The value of MaxClockSkew, which is the allowable time difference between the client machine clock and the InForm server clock, can be modified in the web.config file for the User Management Interface.

If the time difference between the client machine clock and the InForm server machine clock is greater than the value specified by the MaxClockSkew setting, the WCF rejects the SOAP message with a security error, and the operation fails.

The default clock skew is five minutes.

To change the allowable time difference:

  1. Using an editor of your choice, open the User Management Interface web.config file, located at

    <installation_directory>\Provisioning\web.config

  2. Locate the following line, which in the default installation, includes opening comment characters (<!--) and closing comment characters (-->):

    <!--

    <add key="InForm.SDK.Provisioning.Settings.Web.MaxClockSkew" value="00:10:00"/>

    -->

  3. Delete the opening comment characters <!-- and the closing comment characters -->.
  4. Set the value of the clock skew. The format is hours:minutes:seconds.

    For example:

    Time value

    Setting

    10 minutes

    value="00:10:00"

    One hour

    value="01:00:00"

    90 minutes

    value="01:30:00"

  5. Save the file.
