Working on text mode, I select authentication on the main window. Then if I select kerberos and press next I go to the kerberos parameters window. If on that window I made some changes and press back (for example to check If I did enable md5), the values that I've just filled are not remembered, and when I go again through the next button on main window I must retype them again
The authconfig TUI is deprecated and no new features and major improvements such as this one will be done to it.
