PAM -- SRP Password not set

Hi,I ran into a problem when I use SRP telnetd and telnet:

Trying 127.0.0.1...

Connected to GATE (127.0.0.1).

Escape character is '^]'.

[ Negotiating SSL/TLS session ... ]

[ Cipher: ADH-AES256-SHA (256 bits) ]

[ Attempting to verify TLS session parameters... ]

[ Trying SRP ... ]

SRP Username (root): root

[ SRP refuses authentication for 'root' (Password not set) ]

WARNING: unable to verify TLS session parameters. Continue? (Y/N) y

telnetd: Authorization failed.

Connection closed by foreign host.

My configuration:

1. OS

centos 4.2

2. installation steps

1) ./configure --prefix=/usr/local/srp --with-openssl=/root/kernel/openssl-0.9.8a --with-pam

2) make

3) make install

4) cp /usr/local/srp/sbin/eps_chkpwd /sbin/

5) cp /usr/local/srp/bin/passwd /usr/bin/

6) cp /usr/local/srp/bin/login /bin/

7) cp /usr/local/srp/bin/su /bin/

8) cp base/pam_eps/pam_eps_*.so /lib/security/

9) added the fllowing two lines to some files in /etc/pam/d: login, su, passwd, telnet(made by myself) and system-auth

auth required /lib/security/pam_eps_auth.so

passwd required /lib/security/pam_eps_passwd.so

/etc/pam.d/telete

auth required pam_stack.so service=system-auth

auth required /lib/security/pam_eps_auth.so

account required pam_stack.so service=system-auth

passwd required /lib/security/pam_unix.so nullok use_authtok md5 shadow

passwd required /lib/security/pam_eps_passwd.so

session required pam_stack.so service=system-auth

10) run the tconf a! nd generated the key

11) remade the root password and one other and confirmed that they updated shadow, passwd and tpasswd

12) made a new file --- /etc/xinetd.d/telnet

# description: The SRP Telnet server

#serves Telnet connections.

# It uses SRP for authentication.

service telnet

{

disable = no

bind = 127.0.0.1

socket_type = stream

wait = no

user = root

server = /usr/local/srp/sbin/telnetd

server_args = -a valid

log_on_success += DURATION USERID

log_on_failure += USERID

nice = 10

}

What's wrong is this? All contributions gratefully received.
