Module Name: src Committed By: riastradh Date: Tue Jun 20 22:00:00 UTC 2023
Modified Files: src/etc/pam.d: display_manager ftpd sshd su system Log Message: pam: Disable pam_krb5, pam_ksu by default. These are not useful unless you also set up /etc/krb5.conf and a keytab for the host from the Kerberos KDC. But having them enabled by default means that creating /etc/krb5.conf just to enable use of Kerberos for _client-side_ single sign-on creates usability issues.
