Bug 1419735

Just public recap: we need to retest workflow:

1. install ipa-server as self-signed CA
2. issue CA cert signed by
   a) dogtag CA
   b) AD CA
3. use "Self-signed CA certificate → externally-signed CA certificate" method for both types (a and b) of CA cert.
 https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Linux_Domain_Identity_Authentication_and_Policy_Guide/change-cert-chaining.html

4. Run ipa-certupdate
5. Attempt to install replica

It fails in step "[3/5]: Importing RA Key" with: 


    run_step(full_msg, method)
  File "/usr/lib/python2.7/site-packages/ipaserver/install/service.py", line 438, in run_step

Workflow where first IPA server is installed with --external-ca right away works for CA cert issued by DogTag CA. We need to retest and fix issuing with AD CA - bug 1322963 or upstream #5799

Steps as per BZ 1429872 comment #6.

1. Install CA-less ipa-server

root@master ~]# ipa-server-install --ip-address $(ip addr|grep "global"|cut -d " " -f6|cut -d "/" -f1|head -n 1) -r TESTRELM.TEST -n testrelm.test -p 'XXX' -a 'XXX' --setup-dns --forwarder 192.168.222.1 -U --dirsrv-cert-file=./server.p12 --http-cert-file=./server.p12 --dirsrv-pin XXX --http-pin XXX --no-pkinit

==============================================================================
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.

In order for Firefox autoconfiguration to work you will need to
use a SSL signing certificate. See the IPA documentation for more details.
[root@master ~]# 

2. Install CA-less replica

[root@replica1 ~]# ipa-client-install -U --domain testrelm.test --realm TESTRELM.TEST -p admin -w XXX --server master.testrelm.test
[root@replica1 ~]# ipa-replica-install -U --dirsrv-cert-file=./replica.p12 --http-cert-file=./replica.p12 --dirsrv-pin XXX --http-pin XXX -P admin -w XXX --no-pkinit
