I am thinking to enable users by ldap server. Is it possible in the personal cloud environment ?
Yes, but only for your applications (Users), not for Service Center or Lifetime.
Also, you can use an LDAP server to validate the user credentials, but you will not be able to fully integrate (avoiding the need for login) because the server where is your cloud environment won't be in the same domain than your LDAP server.
Hope this answers your question.
thanks for your answer. Are you meaning that I need an enterprise or on premisse version to integrate ldap with Service Center ?
Right now, you would need an On-Premise, as the same restrictions that I referred for the Personal, also apply to the Enterprise Cloud.
But this is currently an hot topic, we may address it in a future version.
