红帽全球峰会6.5. Using certificate profiles and CA ACLs to issue certificates
You can request certificates using a certificate profile when permitted by the Certificate Authority access control lists (CA ACLs). Follow this procedure to request an S/MIME certificate for a user using a custom certificate profile which has been granted access through a CA ACL.
Prerequisites
- Your certificate profile has been created.
- An CA ACL has been created which permits the user to use the required certificate profile to request a certificate.
You can bypass the CA ACL check if the user performing the cert-request command:
-
Is the
adminuser. -
Has the
Request Certificate ignoring CA ACLspermission.
Procedure
Generate a certificate request for the user. For example, using OpenSSL:
$ openssl req -new -newkey rsa:2048 -days 365 -nodes -keyout private.key -out cert.csr -subj '/CN=smime_user'Request a new certificate for the user from the IdM CA:
$ ipa cert-request cert.csr --principal=smime_user --profile-id=smimeOptional: Pass the --ca sub-CA_name option to the command to request the certificate from a sub-CA instead of the root CA.
Verification
Verify the newly-issued certificate is assigned to the user:
$ ipa user-show user User login: user ... Certificate: MIICfzCCAWcCAQA... ...
