Error: Correct the following information" when Common Name includes an underscore

Problem

Symantec E-Commerce and GeoTrust platforms do not allow underscore in the hostname of the Common Name, hence the enrollment fails with an error.

Error Message

Correct the following information.

Website URL to secure is invalid.

Cause

This is due to RFC 1123 where it states:

"However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits. No other symbols, punctuation characters, or white space are permitted. While a hostname may not contain other characters, such as the underscore character (_), other DNS names may contain the underscore."

Solution

Work around

If customer is in need of the CN with underscore in the hostname, they can obtain this from our MPKI SSL platform.
