Hi Michael,
Thanks for your answer. I've realized when I changed the entry 'ce.gluu.info', that I suppose is responsably for show the Asimba DS, and select one specific IdP, I've lost the default configuration and the Asimba DS wasn't showed anymore. I had to reinstall the Gluu Server CE, and now it's working.
I'm not a developer, so perhaps more dumb questions like this will come.
Kind regards.
PS. I don't know if I can close the ticket by myself. So for me it is resolved.
