           Summary: PAM with ssh authentication and pam_krb5 doesn't work
           Product: Portable OpenSSH
           Version: 3.0.2p1
          Platform: UltraSparc
        OS/Version: Solaris
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sshd
        AssignedTo: openssh-unix-dev at mindrot.org
        ReportedBy: b_smith44 at hotmail.com

when authenticating against pam_krb5 before pam_unix the user can not login, 
sshd logs the error "input_userauth_info_response_pam: no authentication 

i don't know why this is failing, this patch fixes the problem by removing the 
check for an authentication context.

users can now login with the pam.conf entry:

sshd auth sufficient /usr/lib/security/$ISA/pam_krb5.so.1
sshd auth required /usr/lib/security/$ISA/pam_unix.so.1 try_first_pass

       debug("got %d responses", nresp);
