tls error with star certificate

[rpoyner]

I'm trying to get https downloads working against an https server where the certificate has a * for the hostname:

*.dept.school.edu

The acutual ipxe host is:

ipxe.dept.school.edu

When I attempt to connect to the https server with an ipxe kernel compiled with DEBUG=tls I get:

TLS 0x24104 server name incorrect (expected ipxe.dept.school.edu, got *.dept.school.edu)

Anyone know of a work around for this case? The star certs are handy, and they work for most https clients, but maybe not for ipxe?

Thanks in Advance
