pam_radius_auth

[Megan]

Good Day,

I am making an attempt to setup sudo authentication on a Centos 5.2
server to work with pam_radius_auth.  I rwant ldap to handle my
regular users (this works already) and I want my privileged users to
authenticate through radius when they use sudo.  I put the below in
/etc/pam.d/sudo and it seems to work fine, except that I need an entry
in /etc/shadow for any user who sudos.    If i remove the user from
/etc/shadow then I get a loop back to the radius authentication.  If I
remove the pam_unix.so entry for auth then I also get a loop back
asking for a password when the radius server Accepted it.  Any ideas?
