IPA 3.x includes a command, ipa-server-certinstall, which will do what you need. This can be a bumpy process with clients and such which is why Dmitri suggested using 4.1, but it should still basically work. It depends greatly on whether the CA issuing the certs is already known by clients (for example being a default CA shipped by NSS and openssl). But I'd step cautiously and ask a lot of questions before you proceed. The IPA certificates are not self-signed. They are issued by a CA controlled by IPA. I think your admin's concerns are related to users getting an unknown CA/cert error. It can be confusing and can train users to accept any SSL certificate they see which is bad. There are some downsides to not using the IPA CA: - no automatic renewal of certificates. This means you need to manually monitor your infrastructure and renew the certificates before they expire. Otherwise your identity infrastructure could go down. - for every replica you set up you will need to get a web and ldap certificate in advance rob > > > On Mon, Oct 13, 2014 at 7:01 PM, Dmitri Pal <d...@redhat.com > <mailto:d...@redhat.com>> wrote: > > On 10/13/2014 06:45 PM, quest monger wrote: >> I did the default IPA install, didnt change any certs or anything. >> As part of that install, it now shows 2 certs, one on port 443 >> (HTTPS) and one on port 636 (LDAPS).
