In trying to get the docusign integration working I am coming across the following error after selecting a document in the Laserfiche Web Client and clicking the "Request Signature with Docusign" button, selecting the recipients, and then clicking the "Request Signature" button:

Error

One or both of Username and Password are invalid.

I have correctly set up the the Account ID, User name, and Password here: http://localhost/laserfiche/Configuration/Configuration.aspx#externalSection

DocuSign Integration ON

Account ID 

User name 

Password

and I have Validated the DocuSign Account here: /laserfiche/options.aspx?repo=OneidaCounty#/advancedpane

DocuSign Account

Email

Password

I have also verified the C:\Program Files\Laserfiche\Web Access\Web Files\Web.config file has the following entry in the <configuration> section:

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="APIServiceSoap">
          <security mode="Transport" />
        </binding>
        <binding name="APIServiceSoap1" />
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="https://www.docusign.net/api/3.0/api.asmx" binding="basicHttpBinding" bindingConfiguration="APIServiceSoap" contract="DocuSignAPI.APIServiceSoap" name="APIServiceSoap" />
    </client>
  </system.serviceModel>

And verified that the C:\Program Files\Laserfiche\Web Access\Web Files\web.config has the following entry in the <configuration> section: 

  <!-- WCF client configuration -->
  <system.serviceModel>
    <client configSource="client.config" />
    <bindings configSource="bindings.config" />
    <!-- LMO/IM block -->
    <behaviors configSource="behaviors.config" />
  </system.serviceModel>

With client.config having:

<client>
  <!-- Change endpoint address to https://demo.docusign.net/api/3.0/credential.asmx if you're using Demo mode with your own Integrators Key -->
  <endpoint address="https://www.docusign.net/api/3.0/credential.asmx" binding="basicHttpBinding" bindingConfiguration="CredentialSoap" contract="CredentialAPI.CredentialSoap" name="CredentialSoap" />
  <!-- Change endpoint address to https://demo.docusign.net/api/3.0/api.asmx if you're using Demo mode with your own Integrators Key -->
  <endpoint address="https://www.docusign.net/api/3.0/api.asmx" binding="basicHttpBinding" bindingConfiguration="APIServiceSoap" contract="DocuSignAPI.APIServiceSoap" name="APIServiceSoap" />
 

And bindings.config having:

<bindings>
  <basicHttpBinding>
    <binding name="APIServiceSoap" closeTimeout="00:01:00" openTimeout="00:01:00"
        receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="true"
        bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
        maxBufferPoolSize="524288" maxBufferSize="50000000" maxReceivedMessageSize="50000000"
        textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"
        messageEncoding="Text">
      <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
          maxBytesPerRead="4096" maxNameTableCharCount="16384" />
      <security mode="TransportWithMessageCredential">
        <transport clientCredentialType="None" proxyCredentialType="None"
            realm="">
          <extendedProtectionPolicy policyEnforcement="Never" />
        </transport>
        <message clientCredentialType="UserName" algorithmSuite="Default" />
      </security>
  </binding>

So, I am confused as to why I am presented with this error. Please advise...
