Change in behavior from 2.5p2 to 2.9p1

[Aaron Dudek]

Under 2.5p2, if I ssh'd back to myself I would get a prompt asking for my 
passphrase, and if that was incorrect it would then ask for my password. 
Assuming I had a authorized_keys file with my identity.pub in it.
Under 2.9.p1 it goes straight to enter password instead of asking for my 
passphrase.
This wouldn't be a problem except that when I have "PasswordAuthentication 
no" I get the following error:
Permission denied (publickey)

Can someone please help me understand why this behavior changed and how to 
fix it if possible. It looks like something to do with using ssh2 from 
looking at the verbose output.


Thanks
Aaron
