RedHat 7.0 release 2.2.17-3 for Alpha.
After adding a user and password in Linuxconf, the message "Error message
from remadmin:** warning **: Unknown type for widget "tree-0.book.main-1-
3.cl." opens in the Terminal Window where linuxconf was launched. The
user and password is added correctly. This does not happen when adding a
user and a password using RedHat 6.2 for Alpha.
Believe this is fixed in the current release
