With Solaris 2.6, editing the PAM configuration policy file, pam.conf, to force users to provide a password even when a trust relationship has been defined using .rhosts or /etc/hosts.equiv. To do this, comment out the following lines in /etc/pam.conf:
rloginauth sufficient /usr/lib/security/pam_rhosts_auth.so.1
rloginauth required /usr/lib/security/pam_unix.so.1
rshauth required /usr/lib/security/pam_rhosts_auth.so.1
