logon cookie is missing when  using Enterprise Browser

We are trying to migrate an ITS SAP application from an Intermec browser of CN51 to an EB v1.7 on TC51.

When logging in,  we get the "Logon with URL parameter not possible;logon cookie is missing" message.

When using default android browser of TC51, we are able to login fine.

We tried the authenication of username and password on the config.xml file but it does not work.

Any help is greatly appreciated.
