+# When you add an entry to the top of this file, add your name, the date, and
+# an explanation of why something is getting masked. Please be extremely
+# careful not to commit atoms that are not valid, as it can cause large-scale
+# breakage, especially if it ends up in the daily snapshot.
+#
+## Example:
+##
+## # Dev E. Loper <developer@gentoo.org> (28 Jun 2012)

+#
+# - Best last rites (removal) practices -
+# Include the following info:
+# a) reason for masking
+# b) bug # for the removal (and yes you should have one)
+# c) date of removal (either the date or "in x days")
+#
+## Example:
+##
+## # Dev E. Loper <developer@gentoo.org> (23 May 2015)

This might not be a good idea on a multi-user system but could reduce slightly the overhead on single-user non-networked systems.
+sys-auth/pambase:mktemp - Enable pam_mktemp module on system auth stack for session handling. This module creates a private temporary directory for the user, and sets TMP and TMPDIR accordingly.
+sys-auth/pambase:nullok - Enable the nullok option with the pam_unix module. This allows people to login with blank passwords.
+sys-auth/pambase:pam_krb5 - Enable pam_krb5 module on system auth stack, as an alternative to pam_unix. If Kerberos authentication succeed, only pam_unix will be ignore, and all the other modules will proceed as usual, including Gnome Keyring and other session modules. It requires sys-libs/pam as PAM implementation.
+sys-auth/pambase:pam_ssh - Enable pam_ssh module on system auth stack for authentication and session handling. This module will accept as password the passphrase of a private SSH key (one of ~/.ssh/id_rsa, ~/.ssh/id_dsa or ~/.ssh/identity), and will spawn an ssh-agent instance to cache the open key.
+sys-auth/pambase:passwdqc - Enable pam_passwdqc module on system auth stack for password quality validation. This is an alternative to pam_cracklib producing warnings, rejecting or providing example passwords when changing your system password. It is used by default by OpenWall GNU/*/Linux and by FreeBSD.
+sys-auth/pambase:securetty - Enable pam_securetty module in the login stack. Not generally relevant anymore as the login stack only refers to local logins and local terminals imply secure access in the first place.
+sys-auth/pambase:sha512 - Switch Linux-PAM's pam_unix module to use sha512 for passwords hashes rather than MD5. This option requires sys-libs/pam version 1.0.1 built against sys-libs/glibc version 2.7, if it's built against an earlier version, it will silently be ignored, and MD5 hashes will be used. All the passwords changed after this USE flag is enabled will be saved to the shadow file hashed using SHA512 function. The password previously saved will be left untouched. Please note that while SHA512-hashed passwords will still be recognised if the USE flag is removed, the shadow file will not be compatible with systems using an earlier glibc version.
