This problem has been fixed in PuTTY 0.62.
Back at the beginning of last month, PuTTY 0.61 was released after four years (!) of development. Since upgrading to this new release, I've noticed the occasional "Access Denied" message when connecting to certain Linux systems at work. The odd thing about this message is that it appears between the user ID prompt and the password prompt; in essence, before I even get the chance to log in! Example output looks something like this:
login as: root Access denied root@myserver's password:
Making things stranger, I can enter the correct password and log in to the system with no problems. As I found out from a commenter on another blog, it turns out this message is due to a new feature in PuTTY 0.61. To prevent this message from appearing, do the following:
- Drill down into the Connection » SSH » Auth » GSSAPI section of your session's configuration
- Uncheck the Attempt GSSAPI authentication (SSH-2 only) option
The phantom access denied message should then go away.
