After reimaging flex appliance 5150 to 2.1, Can't login hostadmin. I entered password default. (P@xxxxxx) The shall said 'login incorrect.' I tried to login before password that i changed, and that happend again.
Funny Things that i tried login root with default password, it works and looks bash style shell.
Anyway, i did re-reimaging to 2.0 and it happen again like before.
