Thanks for the background. Every piece of evidence can help find
the bug :)

I'd recommend copying the IPA template from
/usr/share/ipa/profiles/caIPAserviceCert.cfg, then filling out the
params manually and updating the profile. There are four config
params that require substitutions; fill them out like below:
- policyset.serverCertSet.1.default.params.name=CN=$request.req_subject_name.cn$, o=YOUR-DOMAIN
(note the SINGLE '$'s; they are double '$$' in the template)
- policyset.serverCertSet.5.default.params.authInfoAccessADLocation_0=http://ipa-ca.YOUR-DOMAIN/ca/ocsp
- policyset.serverCertSet.9.default.params.crlDistPointsIssuerName_0=CN=Certificate Authority,o=ipaca
- policyset.serverCertSet.9.default.params.crlDistPointsPointName_0=http://ipa-ca.YOUR-DOMAIN/ipa/crl/MasterCRL.bin
Leave other values unchanged. Import the updated profile by
running:
ipa certprofile-mod caIPAserviceCert --file new.cfg
Then certificates should be issued as expected.
