If you create certificate in ConsoleOne without specifying a purpose, XTier does not function properly. You need to specify a purpose for the authentication to work.
For more information about this issue, see TID 10096804.
An issue occurs with users setting up their Netscape browsers to prompt for the certificate database password each time they want to select a certificate. After they enter the password, the browser appears to hang and in some cases, it eventually times out. This is because of a defect in Netscape. If users enter the URL again without closing the browser, they are prompted to select their certificates again and re-enter their passwords. After the second time, they are given access.
