I am getting an odd error when trying to issue a certificate with an IP
address in its SAN. I am using IPA 4.6.8 on RHEL 7.9, so it's a bit
old, but it should work, AFAIK.
Here is the host for which I want to issue the certificate:
$ ipa host-show
node01-idrac.pemlab.rdu2.redhat.com
Host name:
node01-idrac.pemlab.rdu2.redhat.com
Principal name:
host/node01-idrac.pemlab.rdu2.redhat.com(a)PEMLAB.RDU2.REDHAT.COM
Principal alias:
host/node01-idrac.pemlab.rdu2.redhat.com(a)PEMLAB.RDU2.REDHAT.COM
Password: False
Keytab: False
Managed by:
node01-idrac.pemlab.rdu2.redhat.com
Here is the CSR:
$ openssl req -noout -text -in node01-idrac.csr
Certificate Request:

$ ipa cert-request node01-idrac.csr --certificate-out node01-idrac.crt \
--principal
host/node01-idrac.pemlab.rdu2.redhat.com(a)PEMLAB.RDU2.REDHAT.COM
ipa: ERROR: The service principal for subject alt name 10.11.173.11 in
certificate request does not exist
From my examination of ipaserver/plugins/cert.py, I don't think that
this has anything to do with validation of the IP address, as the
exception seem to be raised before _validate_san_ips ever gets called.
Beyond that, however, I really don't know what's going on.
I've filed this as
https://bugzilla.redhat.com/show_bug.cgi?id=1960041,
but I was wondering if anyone on this list has seen this behavior or can
spot an error that I'm making.
Thanks!
