Thanks Denis, setting the flag on the second Manager seems to have fixed the issue. 

manager.Options.UseDefaultAuthenticationContext = false;

Regards
Marcus

Hi Marcus,

This type of padding error is almost always caused by not setting the "sessionEncryptionKey" correctly if you're doing load balancing. See the following links for more details.

http://www.ideablade.com/forum/forum_posts.asp?TID=2425&title=padding-error-on-azure

http://drc.ideablade.com/xwiki/bin/view/Documentation/deploy-iis#HObjectServer28customconfiguration29

I notice that as soon as this Manager is created, it shares the same SessionKey and IPrinicpal as the main app Entity Manager (created first), this I find strange considering I don't link it to the first manager

In 6.1.6, we implement a new feature that provides single sign on/sign off by default. This means that you no longer have to link EntityManagers. Every EntityManager created now uses a default shared AuthenticationContext class. You can optionally turns off this sharing by setting the Options.UseDefaultAuthenticationContext flag.

See the following 6.1.6 release notes for more details. http://drc.ideablade.com/xwiki/bin/view/Documentation/616-release-notes

Hi Guys,

Devforce Version : 6.1.7
Platform : Silverlight

Getting the subject error while trying to deploy a BOS to IIS 7.0. Here's the scenario;

Our silverlight app has two EntityManagers, one will be remote (stored on clients own IIS server). We have specified the following in the App.Config;

<ideablade.configuration version="6.00" xmlns="http://schemas.ideablade.com/2010/IdeaBladeConfig">
    <logging logFile="log\DebugLog7.xml" />
    <objectServer remoteBaseURL="http://localhost" serverPort="9100" serviceName="EntityService.svc">
      <serviceKeys>
        <serviceKey name="GTPAC" remoteBaseURL="http://testserver" serverPort="81" serviceName="GTPACBOS/EntityService.svc/sl" />
      </serviceKeys>
      <clientSettings isDistributed="true" />
    </objectServer>
  </ideablade.configuration>

The underlying Entity Manager is created using the following;

return new GTPACEntities(new EntityManagerContext(true, null, EntityServiceOption.UseDistributedService, null, null, serviceKey: _userContext.TenantDetails.SERVICE_KEY));

I notice that as soon as this Manager is created, it shares the same SessionKey and IPrinicpal as the main app Entity Manager (created first), this I find strange considering I don't link it to the first manager and I implement a second Login Manager on the remote BOS which doesn't seem to be resolving. The login itself seems to succeed, but as soon as I try to query the manager for an Entity, the below Padding error occurs..

The debug log on the remote BOS is as follows;

It should be noted, that when I deploy to my local (development) IIS server, everything works fine, however, as soon as I try to deploy to the remote IIS server, the padding error occurs.

Any help GREATLY appreciated..

Thanks
Marcus
