Hi,

I got another error when trying the command again:

The ipa-certupdate command failed.

I have the same error in both clients and server.

Hello,
Enrolling new users is failing because of the certificate issue (curl

Hi,

you need to perform "kinit admin" before running ipa-certupdate
(ipa-certupdate needs to be authenticated via kerberos to grab the
certificates from the LDAP server).

Also note that ipa-certupdate needs to be run on all IPA machines
(clients and servers).

     The clients need to trust the issuer of your CA cert.

     Try ipa-cacert-manage install to install the chain

     Then on each already-enrolled client run ipa-certupdate

     New clients should get the chain upon enrollment.

Hi,

I would start by checking which certificate is used by the httpd server. You can try to open the URI in a web browser and view the certificate. Note which certificate authority provided the cert, and compare with what you are expecting.

Then check if /etc/ipa/ca.crt contains the CA certificate:
openssl x509 -noout -text -in /etc/ipa/ca.crt

If it is not the case, you can copy-paste the CA cert in the file (append the cert but do not erase the other ones).

HTH,
Flo
