=head1 NAME |
| |
|
| |
Apache::lonacc - Cookie Based Access Handler |
| |
|
| |
=head1 SYNOPSIS |
| |
|
| |
Invoked (for various locations) by /etc/httpd/conf/srm.conf: |
| |
|
| |
PerlAccessHandler Apache::lonacc |
| |
|
| |
=head1 INTRODUCTION |
| |
|
| |
This module enables cookie based authentication and is used |
| |
to control access for many different LON-CAPA URIs. |
| |
|
| |
Whenever the client sends the cookie back to the server, |
| |
this cookie is handled by either lonacc.pm or loncacc.pm |
| |
(see srm.conf for what is invoked when). If |
| |
the cookie is missing or invalid, the user is re-challenged |
| |
for login information. |
| |
|
| |
This is part of the LearningOnline Network with CAPA project |
| |
described at http://www.lon-capa.org. |

SSO or by checkauthen.pm, if a valid cookie was found. The latter case can |

be identified by the third arg ($usename), except when lonacc is called in |

successful authentication) -- no cookie set yet. For that particular case |

i.e., for a protected link, with launch from another CMS, and user information |

authentication will be required. If SSO authentication is with a username |

in the launch URL, then $r->user() will be unset and /adm/relaunch will be |

| Apache::lonacc - Cookie Based Access Handler |
|
| |
|
| =head1 SYNOPSIS |
|
| |
|
| Invoked (for various locations) by /etc/httpd/conf/srm.conf: |
|
| |
|
| PerlAccessHandler Apache::lonacc |
|
| |
|
| =head1 INTRODUCTION |
|
| |
|
| This module enables cookie based authentication and is used |
|
| to control access for many different LON-CAPA URIs. |
|
| |
|
| Whenever the client sends the cookie back to the server, |
|
| this cookie is handled by either lonacc.pm or loncacc.pm |
|
| (see srm.conf for what is invoked when). If |
|
| the cookie is missing or invalid, the user is re-challenged |
|
| for login information. |
|
| |
|
| This is part of the LearningOnline Network with CAPA project |
|
| described at http://www.lon-capa.org. |
|
