Skip to Installation

Before You Begin

It is strongly recommended that you take the following precautions to ensure that you will be able to install your Entrust SSL certificate:

    ! Do not use commas in any of the fields you fill in when creating your Certificate Signing Request (CSR). Commas are interpreted as the end of the field and will cause an invalid CSR to be generated.

    ! Do not use any of the following characters in the Web server Distinguished Name: ! @ # $ % ^ * ( ) ~ ? > < & / \

    ! When you generate your CSR, make sure you are logged in as an Administrator to the computer that hosts your Web server.

Testing of this product was used on a Mac OS X 10.4 running the Kerio Webstar 5 Trial.
