UIPasswordAuth

By default, the IPA Web UI uses Kerberos Negotiate to perform a single sign-on login. This is handled automatically in Firefox if it is properly configured and you have a TGT.

There are some cases where this is not possible, such as an unsupported browser or operating system (Windows for example).

One alternative is to have the Web UI fall back to a Basic Authentication-type dialog box prompting for username/password. To do this edit /etc/httpd/conf.d/ipa.conf

Set the value of KrbMethodK5Passwd to on and restart the httpd service (/sbin/service httpd restart)

The web server will first attempt to use Kerberos Negotiate to log the user in. If that fails then the user will be presented with a login prompt.
