ipa-client-install --unattended stalls with a prompt for user input

What I expected to happen:

According to the documentation, when ipa-client-install is executed with --unattended or -U it will not prompt for user input.

What happened instead:

When ipa-client-install reaches PAM configuration, it prompts for user input.

root@ubuntu-client:~# ipa-client-install --hostname=`hostname -f` --domain=example.com --server=`/usr/bin/dig SRV _kerberos-master._tcp.example.com. +short | /usr/bin/head -n 1 | /usr/bin/awk '{print $4}' | sed 's/\.$//'` --enable-dns-updates --unattended --password='secret'
DNS domain 'example.com' is not configured for automatic KDC address lookup.
KDC address will be set to fixed value.

Discovery was successful!
Hostname: ubuntu-client.example.com
Realm: EXAMPLE3.COM
DNS Domain: example.com
IPA Server: ipa-server.example.com
BaseDN: dc=example,dc=com

Synchronizing time with KDC...
Unable to sync time with IPA NTP server, assuming the time is in sync.
Enrolled in IPA realm EXAMPLE.COM
Created /etc/ipa/default.conf
Domain example.com is already configured in existing SSSD config, creating a new one.
The old /etc/sssd/sssd.conf is backed up and will be restored during uninstall.
Configured /etc/sssd/sssd.conf
Configured /etc/krb5.conf for IPA realm EXAMPLE.COM

this should be fixed in trusty, reopen if not
