I'm trying to install BorderManager 3.7

I get to the point where it asks me to login as admin

I enter the correct password but it tells me it's invalid.

I go to console one & netware remote manager and use the same login
details,
(just to check). They both let me in.

login name: admin
context: .cn=admin.o=(our organisation)
password: the same one used for console one & remote manager

I'm trying all of this from the server

What am I doing wrong
