I use :
Every time, when i reboot the Pi ( by turning it off and on again, or via "sudo reboot" ) and i log in the first time. I have to enter my password twice. If i log "out" and "in" while the Pi is running i only need to enter the password once.Linux raspberrypi 3.1.9+ #90 Wed Apr 18 18:23:05 BST 2012 armv6l
I think the second password entering is the sudo password, but why is this, and the better question, how can i turn the second password dialog off ?
Here is a login screendump if i login via ssh :
Using username "corpsman".
