here is the problem.
I was trying to connect via explorer to my bubba (as a network share).
this somehow did not work. so, continued reading this forum.
that brought me to Putty.
I've connected via Putty to my bubba with my username.
logging on for the first time, it asked
So...I did.You are required to change your password immediately (root enforced)
this solved the mapping as a share problem...but strangely enough: mapping works with my old password.
logging on to the admin pages in my browser, required the new password.
how is this possible?
