done configuring krb5kdc.


Additional info:

Well, I'm not a python guy, so I took strace in use to figure it out. When looking at the log created by strace it became obvious that it was searching for tools under /usr/kerberos/sbin which simply doesnt exist.

The different packages install under /usr/sbin directly.

So, the workaround to fix it was simply:
# mkdir -p /usr/kerberos/sbin ; cd /usr/sbin ; for FILE in $(ls k*) ; do ln -s /usr/sbin/$FILE /usr/kerberos/sbin ; done

---

However, when I passed that small error I stumbled upon another one. 
It was trying to use /usr/lib/mozldap/ldappasswd when setting the admin password. But, this wasnt installed seeing as:

# yum deplist ipa-server | grep -c mozldap-tools
0

The fix, being the obvious:
# yum install mozldap-tools

Then my ipa-server-install went through perfectly :-)
