Using OCSP with Apache and mod_nss on CentOS 7
Posted on Tue 17 January 2017 in System Administration
Following steps will guide you how to configure OCSP with Apache and mod_nss
In this example, we will configure client certificate authentication using mod_nss and OCSP.
For this setup, we will use two servers
- cybertron.testrelm.test
- tiger.testrelm.test
cybertron will be FreeIPA server and tiger will be httpd server.
Let us get started -
Installing FreeIPA server on cybertron
FreeIPA provides OCSP server, so we will install and configure FreeIPA server.
[root@cybertron ~]# yum install -y ipa-server ipa-server-dns
[root@cybertron ~]# ipa-server-install --ip-address $(ip addr|grep "global"|cut -d " " -f6|cut -d "/" -f1|head -n 1) -r testrelm.test -p 'Secret123' -a 'Secret123' --setup-dns --forwarder 192.168.12.255 -U
The log file for this installation can be found in /var/log/ipaserver-install.log
==============================================================================
This program will set up the IPA Server.
This includes:
* Configure a stand-alone CA (dogtag) for certificate management
* Configure the Network Time Daemon (ntpd)
* Create and configure an instance of Directory Server
* Create and configure a Kerberos Key Distribution Center (KDC)
* Configure Apache (httpd)
* Configure DNS (bind)
WARNING: conflicting time&date synchronization service 'chronyd' will be disabled
in favor of ntpd
Warning: skipping DNS resolution of host cybertron.testrelm.test
The domain name has been determined based on the host name.
Checking DNS domain testrelm.test., please wait ...
Checking DNS forwarders, please wait ...
The IPA Master Server will be configured with:
Hostname: cybertron.testrelm.test
IP address(es): 192.168.12.1
Domain name: testrelm.test
Realm name: TESTRELM.TEST
BIND DNS server will be configured to serve IPA domain with:

==============================================================================
Setup complete
Next steps:
1. You must make sure these network ports are open:
TCP Ports:
* 80, 443: HTTP/HTTPS
* 389, 636: LDAP/LDAPS
* 88, 464: kerberos
* 53: bind
UDP Ports:
* 88, 464: kerberos
* 53: bind
* 123: ntp
2. You can now obtain a kerberos ticket using the command: 'kinit admin'
This ticket will allow you to use the IPA tools (e.g., ipa user-add)
and the web user interface.
Be sure to back up the CA certificates stored in /root/cacert.p12
These files are required to create replicas. The password for these
files is the Directory Manager password
Create a user
Now, we will create a FreeIPA User which will be used in client authentication.
[root@cybertron ~]# echo Secret123 | kinit admin Password for admin@TESTRELM.TEST: [root@cybertron temp]# echo Secret123 | ipa user-add --first testuser1 --last testuser1 testuser1 --password ---------------------- Added user "testuser1" ---------------------- User login: testuser1 First name: testuser1 Last name: testuser1 Full name: testuser1 testuser1 Display name: testuser1 testuser1 Initials: tt Home directory: /home/testuser1 GECOS: testuser1 testuser1 Login shell: /bin/sh Principal name: testuser1@TESTRELM.TEST Principal alias: testuser1@TESTRELM.TEST Email address: testuser1@testrelm.test UID: 539800003 GID: 539800003 Password: True Member of groups: ipausers Kerberos keys available: True

Import CA certificate and Server certificate on httpd server
Import previously created CA certificate and server certificate in httpd's NSSdb
First export CA certificate and server certificate from cybertron

Now, import these certificates on httpd server i.e., tiger
[root@tiger alias]# pwd
/etc/httpd/alias
[root@tiger alias]# pk12util -i server1.p12 -d .
Enter password for PKCS12 file:
pk12util: no nickname for cert in PKCS12 file.
