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?

Hi Megan,
I have a similar set up, except that instead of using pam_ldap, I'm
using pam_unix to authentication users by making use of libnss-ldapd.
My /etc/nsswitch.conf file looks like:
passwd: compat ldap
group: compat ldap
shadow: compat ldap
...
And my LDAP entries contain objectClass: shadowAccount, and all the
attributes that class requires.
