/**
 * This test checks to see if the nntp password failure is handled correctly.
 * The steps are:
 *   - Have an invalid password in the password database.
 *   - Check we get a prompt asking what to do.
 *   - Check retry does what it should do.
 *   - Check cancel does what it should do.
 *   - Re-initiate connection, this time select enter new password, check that
 *     we get a new password prompt and can enter the password.
