Title:
krb5-otp package not being installed when ipa-server-install
Status in freeipa package in Ubuntu:
Fix Released
Bug description:
While using Freeipa server with an external RADIUS server (which is in turn
is connected to an OTP authenticator), freeipa-server fails to load the
required krb5-otp module.
That's because the module is simply not there and every request send by an
user using FAST/OTP will fail. This is the message on /var/log/auth:
NEEDED_PREAUTH: johndoe@REALM for krbtgt/REALM, Additional pre-
authentication required
The user gets (note that he is not prompted for OTP, the request simply dies):

kinit: Generic preauthentication failure while getting initial credentials
Solution:
$ sudo apt-get install krb5-otp
$ sudo service krb5-kdc restart
$ sudo service krb5-admin-server restart
After that everything works as expected:
