Known Problems

Some browsers running on Linux were not able to acquire a certificate from the iPlanet enrollment system. The browsers that failed were Galeon 1.2.x and Opera 6.0.1. The Mozilla 1.0 browser worked fine and could export the certificate which could be imported into the other browsers that could not enroll directly. We have not yet found a browser that supports dual key pair generation. Other browsers may work, follow the prompts they provide.
