Publishing in a webport and users access

Hello,

I published a protocol under protocols\web services\....\myProtocol

This protocol works fine if logged with my account.

If logged with someone else he will get the following error:

'{7289936F-6811-D772-8CA7-16C5E5E6ACCC}' did not run successfully because an error occurred.

A communications error occurred: wsRunner::sci__LaunchProtocol (Unable to load protocol "{7289936F-6811-D772-8CA7-16C5E5E6ACCC}"vcJobRunner::LaunchFromXML: Pipeline Pilot exception rethrownwsRunnerUtils::LaunchProtocolFromXML: Pipeline Pilot exception rethrownwsRunnerUtils::LaunchProtocolByName: Pipeline Pilot exception rethrownwsRunner::LaunchJob: Pipeline Pilot exception rethrown).Please check that the server is running normally.

This error appears when the user click a button that calls a protocol (an "input form" component define which protocol to call) and display the results in a new window.

Thanks for your help

Florent
