Just in case someone else runs across this. I was trying to install nowssbe2 into an existing tree, that had 1 NetWare 6.5 server. I would get to the point of putting in all of the information and would click next and it would fail and take me right back to the edir install page.

Thanks to an answer in another post from David Parker, there is a log file /var/opt/simba/server.log that holds the failed information.

It said authentication failed. I tried the username and password multiple times. The user I was using had a password with a special character in it.

I created a new user and gave it root rights and gave it a password with just lowercase letters and numbers.

It worked. :)

Hope this helps someone else.
