.It Li k5login_directory = Va directory
Alternative location for user .k5login files. Tokens in the form of
%{luser} are expanded to the name of the user whose .k5login file is
%needed.
.It Li k5login_authoritative = Va boolean
If true then if a principal is not found in k5login files then
krb5_userok() will not fallback on principal to username mapping.
.It Li kuserok = Va rule ...
Specifies krb5_kuserok(3) behavior. If multiple values are given, then
krb5_kuserok(3) will try them in order until one succeeds or all fail.
Rules are implemented by plugins, with three built-in plugins described
below. Default: USER-K5LOGIN SIMPLE.
.It Li kuserok = Va SIMPLE
If set then krb5_userok(3) will use principal to username mapping (see
auth_to_local below). If the principal maps to the requested username
then access is allowed.
.It Li kuserok = Va SYSTEM-K5LOGIN[:directory]
If set then krb5_userok(3) will use k5login files named after the
.Va luser
argument to krb5_kuserok(3) in the given directory or in
/etc/k5login.d/. If a directory is given then tokens will be expanded;
the %{luser} token will be replaced with the
.Va luser
argument to krb5_kuserok(3). K5login files are text files, with each
line containing just a principal name; principals apearing in a user's
k5login file are permitted access to the user's account. Note: this rule
performs no ownership nor permissions checks on k5login files.
.It Li kuserok = Va USER-K5LOGIN
If set then krb5_userok(3) will use ~luser/.k5login and
~luser/.k5login.d/*. User k5login files and directories must be owned
by the user and must not have world nor group write permissions.
