h1. ERF12-5287: Unable to create realm entry

Possible solutions to this issue:

h2. Upgraded IPA 3.x to 4.x

If you upgraded IPA from 3 to 4, the permissions system has changed and the custom permissions foreman needs are not migrated correctly.

Re-run `foreman-prepare-realm` from a server with the IPA version *4* client tools installed (such as the FreeIPA server itself).

h2. Expired Keytab

Do you see an error like this in /var/log/foreman-proxy/proxy.log?

<pre>

ERROR -- : Failed to initailize credentials cache from keytab: krb5_get_init_creds_keytab: Decrypt integrity check failed

</pre>

Your Keytab may be expired. The keytab expiration follows your password expiration policies.

You can get a new one by:

<pre>

# kinit admin@EXAMPLE.COM (or other suitable IPA admin)

# ipa-getkeytab -s ipa01.example.com -p realm-proxy@EXAMPLE.COM -k /etc/foreman-proxy/freeipa.keytab

# chown foreman-proxy:foreman-proxy /etc/foreman-proxy/freeipa.keytab

</pre>

h2. Wrong Size Error

Do you see an error like this in /var/log/foreman-proxy/proxy.log?

<pre>

E, [2014-11-03T15:23:02.715791 #21273] ERROR -- : Wrong size. Was 307, should be 191

</pre>

This is due to a bug in Ruby: 

  https://bugs.ruby-lang.org/issues/8182

This has been fixed in RHEL 7.1 + rebuilds, please run @yum update ruby@.  The relevant bugzilla

is: https://bugzilla.redhat.com/show_bug.cgi?id=1071187

On 7.0, you can temporarily work around the problem by commenting these out on lines 505-506 in

/usr/share/ruby/xmlrpc/client.rb:

<pre>

      #elsif expected != "<unknown>" and expected.to_i != data.bytesize and resp["Transfer-Encoding"].nil?

            #  raise "Wrong size. Was #{data.bytesize}, should be

            #  #{expected}"

</pre>
