SUDO: pam_authenticate: Module is Unknown
 

Hey guys. Any time I run SU or SUDO from any user (excluding root) I get this message: pam_authenticate: Module is Unknown.

Can anyone help me out? I've even tried making new users and they still get the same message.

I'm using Ubuntu 5.10.

Here is a partial listing from my /etc/pam.d directory. As you can see there is a file for every type of login service.

/etc/pam.d/rpasswd
/etc/pam.d/samba
/etc/pam.d/shadow
/etc/pam.d/squid
/etc/pam.d/sshd
/etc/pam.d/su
/etc/pam.d/sudo
/etc/pam.d/useradd
/etc/pam.d/vlock
/etc/pam.d/vsftpd

Here is the content of my /etc/pam.d/su file.

$ cat /etc/pam.d/su
#%PAM-1.0
auth sufficient pam_rootok.so
auth required pam_unix2.so nullok #set_secrpc
account required pam_unix2.so
password required pam_pwcheck.so nullok
password required pam_unix2.so nullok use_first_pass use_authtok
#session required pam_homecheck.so
session required pam_unix2.so debug # none or trace

More information is available at /usr/share/doc/packages/pam/html.

I logged into root and changed the file to match yours, but still, no change.

Maybe you don't have all of the modules installed. The file that I copied here was just a configuration file. You still need the module. Check the documentation on your system disk.
