Hi Team,

 

We need your help or support

 

I have a master IPA server and 2 Replica IPA Servers, i want to install third party certificates in my setup

 

a. master.ipa.example.com

b. replica1.ipa.example.com

c. replica2.ipa.example.com

 

 

1. Generated new CSR/wildcard certificate on master IPA server for the domain "*.ipa.example.com" and shared to third party vendor and they have shared two zip files one for apache and other for tomcat as shown below, i see crt and pem files in zip files as shown below after unzip

 

a. _.ipa.onmobile.com_Apache.zip

b. _.ipa.onmobile.com_TOMCAT.zip

 

unzipped:

 

[root@dir01 tmp]# tree Apache/

Apache/

├── 1f1f7ab616938168.crt

├── 1f1f7ab616938168.pem

├── gd_bundle-g2-g1.crt

└── _.ipa.onmobile.com_Apache.zip

 

0 directories, 4 files

 

 

[root@dir01 tmp]# tree Tomcat/

Tomcat/

├── 1f1f7ab616938168.crt

├── 1f1f7ab616938168.pem

├── gd_bundle-g2-g1.crt

├── gdig2.crt.pem

└── _.ipa.onmobile.com_TOMCAT.zip

 

0 directories, 5 files

 

 

2. Followed the Redhat documentation but not understood which of the following one is applicable in my case for the received certificates

 

Installing Third-Party Certificates for HTTP or LDAP

 

Installing a CA Certificate Manually

 

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/linux_domain_identity_authentication_and_policy_guide/third-party-certs-http-ldap

 

 

Can you please let us know the step by step procedure that how to install the certificates


The certificate that you received has been signed by the vendor's CA (Certificate Authority). This CA needs to be trusted by IPA, this is achieved by following the steps from "Installing a CA Certificate Manually".
Note that the vendor may provide you with a CA chain, in which case the top-level CA and all the intermediate CAs need to be trusted by IPA.

When the CA chain is trusted, you can then install the new certificate for apache, following "Installing Third-Party Certificates for HTTP or LDAP".

 

can you please also comment on below query

 

3. If i install the certificate will it get replaced in "/etc/pki/pki-tomcat/alias/" database as well? along with httpd and dirsrv databases ?

/etc/pki/pki-tomcat/alias/

/etc/httpd/alias/

/etc/dirsrv/slapd-IPA-EXAMPLE-COM

 

It depends on which certificate you want to replace:
- If ipa-server-install is run with --http, the provided certificate will replace the Server-Cert in /etc/httpd/alias. This is the server certificate for Apache/httpd.
- If ipa-server-install is run with --dirsrv, the provided certificate will replace the Server-Cert in /etc/dirsrv/slapd-IPA-EXAMPLE-COM. This is the server certificate for the LDAP server.

The command does not replace the certificate in /etc/pki/pki-tomcat/alias/. This NSS database contains the certificates related to PKI (the Certificate Server for IPA).

The instructions from "Installing a CA Certificate Manually" add the CA chain in the 3 NSS databases you mentioned (they do not replace IPA CA but rather add new CA).

Hope this clarifies,
flo

 

Please let us know if any more details required
