I run into 2 scenarios when I do that.
It either gets to the page where it asks to seup the amdin password, but it asks for the old one none of which work, or it lets me set is but when I do it wouldnt let me log in.
Just to confirm, I an using "admin" ad the username.
Not sure what you mean by "on the last page add LDAP users will be administrators".
Thank you!
