>Description:

	I have some keys in the authorized_keys file with some limitational
	flags:
	no-pty,no-port-forwarding,no-agent-forwarding 1024 35 ..key...

	If add another key _after_ this one, the flags seem to apply to it
	too, even though its line does not have them. no-pty is the most
	noticable one.

>How-To-Repeat:

	Put a couple of keys with no-pty,no-port-forwarding and
	no-agent-forwarding flags in front of your regular keys.
	See, if you can still login normally.

>Fix:

	Make sure the keys with the special flags are at the bottom of
	the file. Not a complete work-around, since the flags may be
	mixed for different keys.
