.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This is a template for authorizer plugins. To define a new type of
authorizer, you need only inherit from this class and define an
\&\fIauthenticate()\fR method. This method takes two arguments: the username
and password and returns an empty list if authentication fails, or a
list of (username, fullname, email) if authentication succeeds (fullname
and email are optional).
.PP
In addition, you may override the \fIuser_in_group()\fR method, which takes
two argumetns: the username and group. Return true if the user belongs
to the group, and false otherwise.
.PP
Other methods you may wish to override include:
.PP
.Vb 5
\& * authentication_hint()
\& * authentication_help()
\& * configure_form()
\& * reconfigure()
\& * credentials()
.Ve
.PP
These are described below.

.ie n .IP "$boolean = $plugin\->authenticate($username,$password)" 4
.el .IP "\f(CW$boolean\fR = \f(CW$plugin\fR\->authenticate($username,$password)" 4
.IX Item "$boolean = $plugin->authenticate($username,$password)"
Return true if username and password are correct. False otherwise.
.ie n .IP "$boolean = $plugin\->user_in_group($username,$groupname)" 4
.el .IP "\f(CW$boolean\fR = \f(CW$plugin\fR\->user_in_group($username,$groupname)" 4
.IX Item "$boolean = $plugin->user_in_group($username,$groupname)"
Return true if user belongs to group. False otherwise.
.SS "Methods that you may want to customize"
.IX Subsection "Methods that you may want to customize"
.ie n .IP "$message = $plugin\->authentication_hint" 4
.el .IP "\f(CW$message\fR = \f(CW$plugin\fR\->authentication_hint" 4
.IX Item "$message = $plugin->authentication_hint"
Returns a message printed at the top of the login dialog, that will
help the user know which credentials he is expected to present. For
example, returning \*(L"Acme Corp Single Sign-on\*(R" will present the user
with \*(L"Please log into your Acme Corp Single Sign-on\*(R".
.Sp
The default behavior is to take this value from the \*(L"login hint\*(R"
option in a stanza named [AuthPlugin:plugin]. Example:
.ie n .IP "$message = $plugin\->authentication_help" 4
.el .IP "\f(CW$message\fR = \f(CW$plugin\fR\->authentication_help" 4
.IX Item "$message = $plugin->authentication_help"
Returns a message printed at the bottom of the login dialog. It is
expected to be used for a help message or link that will give the user
help with logging in. For example, it can take him to a link to reset
his password.
.Sp
The default behavior is to take this value from the \*(L"login help\*(R"
option in a stanza named [AuthPlugin:plugin].
.Sp
.Vb 3
\& [AuthPlugin:plugin]
\& login hint = your Acme Corp Single Sign\-on Account
\& login help = Recover forgotten password
.Ve
.SS "Methods that you may want to override"
.IX Subsection "Methods that you may want to override"
.ie n .IP "$html = $plugin\->\fIconfigure_form()\fR" 4
.el .IP "\f(CW$html\fR = \f(CW$plugin\fR\->\fIconfigure_form()\fR" 4
.IX Item "$html = $plugin->configure_form()"
This method returns the contents of the login form. The default
behavior is to produce two text fields, one named 'name' and the
other named 'password'.
.ie n .IP "$plugin\->\fIreconfigure()\fR" 4
.el .IP "\f(CW$plugin\fR\->\fIreconfigure()\fR" 4
.IX Item "$plugin->reconfigure()"
This method is called to copy the values from the filled-out form into
the plugin's hash of configuration variables. If you add fields to
\&\fIconfigure_form()\fR will you need to adjust this method as well.
.ie n .IP "$plugin\->\fIconfig_defaults()\fR" 4
.el .IP "\f(CW$plugin\fR\->\fIconfig_defaults()\fR" 4
.IX Item "$plugin->config_defaults()"
Set up defaults for the configuration hash. Use this if you wish to
default to a particular username.
.ie n .IP "$plugin\->\fIcredentials()\fR" 4
.el .IP "\f(CW$plugin\fR\->\fIcredentials()\fR" 4
.IX Item "$plugin->credentials()"
This returns a two-element list containing the username and password
last entered into the authentication dialog. It reads these values
from the configuration hash returned by \f(CW$self\fR\->\fIconfiguration()\fR.
If you add additional types of credentials to the login dialog, you
may need to override this method.
