[Pki-users] SubjectAltName - how?

Hi all,

I have Dogtag 10.3.3 installed from COPR @pki effort onto a CentOS 7.2
(build 1511) system.

I can request and approve various different certs through the system
successfully and have it working properly with SSL client certificates in
Chrome.

What I haven't been able to figure out is how to generate a server SSL Cert
that has SubjectAltName entries in it.   An example cnf file I have tried
is

[...]
[ v3_req ]

# Extensions to add to a certificate request

basicConstraints = CA:FALSE
keyUsage = nonRepudiation, digitalSignature, keyEncipherment
subjectAltName = @alt_names

[ alt_names ]
DNS.1 = demo.myhome.com
DNS.2 = demo
DNS.3 = demo.prod.myhome.com

[...]

This generates a valid CSR with the SubjectAltNames in it.   However when I
send it through to be approved on Dogtag, the SAN gets removed.  How do I
setup a profile in Dogtag to allow this CSR with SAN get approved?

Thanks
ian
