Introduction to Pam-krb5

pam-krb5 provides a Kerberos v5 PAM module that supports authentication, user ticket cache handling, simple authorization (via .k5login or checking Kerberos principals against local usernames), and password changing. It can be configured through either options in the PAM configuration itself or through entries in the system krb5.conf file, and it tries to work around PAM implementation flaws in commonly-used PAM-enabled applications such as OpenSSH and xdm.

Configuring

If you want to authenticate passwords against Kerberos add pam_krb5.so to the pam system-auth file. The following commands insert pam_krb5.so after pam_unix.so in /etc/pam.d/system-auth:

sed -i "/auth.*pam_unix.so/a\auth       sufficient   pam_krb5.so try_first_pass" /etc/pam.d/system-auth &&
sed -i "/account.*pam_unix.so/a\account    required     pam_krb5.so" /etc/pam.d/system-auth &&
sed -i "/password.*pam_unix.so/a\password   sufficient   pam_krb5.so" /etc/pam.d/system-auth &&
sed -i "/session.*pam_unix.so/a\session    sufficient   pam_krb5.so" /etc/pam.d/system-auth
