紧急请助：PAM在suse9下不工作！！

floriawll

我在Suse9下配置/etc/pam.d/sshd, 然后重起：/etc/init.d/sshd.
退出后重新登陆，PAM不起作用！
vi /etc/ssh/sshd_config

...............................
# Set this to 'yes' to enable PAM authentication (via challenge-response)
# and session processing. Depending on your PAM configuration, this may
# bypass the setting of 'PasswordAuthentication' and 'PermitEmptyPasswords'
UsePAM yes

AllowTcpForwarding yes
#GatewayPorts no
X11Forwarding yes
#X11DisplayOffset 10
#X11UseLocalhost yes
#PrintMotd yes

..................................

但是，在Redhat EL4和Miracle下都可以正常工作。
请问：Suse9 的PAM是不是比较特殊？需要怎么配置？谢谢~~
