Hi everyone, I have several redhat 4 and 5 machines authenticating successfully against our ldap servers. I used authconfig to configure the clients and everything works great, ssh, vsftp, etc. However, for some reason, I always see a log entry similar to the following in /var/log/secure, even though the login works; Apr 10 08:34:27 server1 sshd[30937]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=137.21.80.195 user=user1 Here is the contents of /etc/nsswitch.conf cat /etc/nsswitch.conf | grep -v \# passwd: files ldap shadow: files ldap group: files ldap hosts: files dns bootparams: nisplus [NOTFOUND=return] files ethers: files netmasks: files networks: files protocols: files ldap rpc: files services: files ldap netgroup: files ldap publickey: nisplus automount: files ldap aliases: files nisplus Any ideas? Thanks for your help. Aaron
