Changes
An {{UBIK Client}} establishes a secure connection to the webservice, therefore a certificate has to be provided and installed on the [http://www.iis.net/ IIS] server running {{UBIK}}. If a genuine Root Authority Certificate is already available this can be used. Otherwise, a temporary developer certificate might be used for development and testing.
{{Attention|In both cases the service itself needs a valid service certificate which refers to the root authority.}}
