+=== ActivityPub ===
+Contributors: automattic, pfefferle, mediaformat, mattwiebe, akirk, jeherve, nuriapena, cavalierlife
+Tags: OStatus, fediverse, activitypub, activitystream

+License URI: http://opensource.org/licenses/MIT
+
+The ActivityPub protocol is a decentralized social networking protocol based upon the ActivityStreams 2.0 data format.
+
+== Description ==
+
+Enter the fediverse with **ActivityPub**, broadcasting your blog to a wider audience! Attract followers, deliver updates, and receive comments from a diverse user base of **ActivityPub**\-compliant platforms.
+
+With the ActivityPub plugin installed, your WordPress blog itself function as a federated profile, along with profiles for each author. For instance, if your website is `example.com`, then the blog-wide profile can be found at `@example.com@example.com`, and authors like Jane and Bob would have their individual profiles at `@jane@example.com` and `@bobz@example.com`, respectively.
+
+An example: I give you my Mastodon profile name: `@pfefferle@mastodon.social`. You search, see my profile, and hit follow. Now, any post I make appears in your Home feed. Similarly, with the ActivityPub plugin, you can find and follow Jane's profile at `@jane@example.com`.
+
+Once you follow Jane's `@jane@example.com` profile, any blog post she crafts on `example.com` will land in your Home feed. Simultaneously, by following the blog-wide profile `@example.com@example.com`, you'll receive updates from all authors.
+
+**Note**: if no one follows your author or blog instance, your posts remain unseen. The simplest method to verify the plugin's operation is by following your profile. If you possess a Mastodon profile, initiate by following your new one.
+
+The plugin works with the following tested federated platforms, but there may be more that it works with as well:
+
+* [Mastodon](https://joinmastodon.org/)
+* [Pleroma](https://pleroma.social/)/[Akkoma](https://akkoma.social/)
+* [friendica](https://friendi.ca/)
+* [Hubzilla](https://hubzilla.org/)
+* [Pixelfed](https://pixelfed.org/)
+* [Socialhome](https://socialhome.network/)
+* [Misskey](https://join.misskey.page/)
+* [Firefish](https://joinfirefish.org/) (rebrand of Calckey)
+
+Some things to note:
+
+1. The blog-wide profile is only compatible with sites with rewrite rules enabled. If your site does not have rewrite rules enabled, the author-specific profiles may still work.
+1. Many single-author blogs have chosen to turn off or redirect their author profile pages, usually via an SEO plugin like Yoast or Rank Math. This is usually done to avoid duplicate content with your blog’s home page. If your author page has been deactivated in this way, then ActivityPub author profiles won’t work for you. Instead, you can turn your author profile page back on, and then use the option in your SEO plugin to noindex the author page. This will still resolve duplicate content issues with search engines and will enable ActivityPub author profiles to work.
+1. Once ActivityPub is installed, *only new posts going forward* will be available in the fediverse. Likewise, even if you’ve been using ActivityPub for a while, anyone who follows your site, will only see new posts you publish from that moment on. They will never see previously-published posts in their Home feed. This process is very similar to subscribing to a newsletter. If you subscribe to a newsletter, you will only receive future emails, but not the old archived ones. With ActivityPub, if someone follows your site, they will only receive new blog posts you publish from then on.
+
+So what’s the process?
+
+1. Install the ActivityPub plugin.
+1. Go to the plugin’s settings page and adjust the settings to your liking. Click the Save button when ready.
+1. Make sure your blog’s author profile page is active if you are using author profiles.
+1. Go to Mastodon or any other federated platform, and search for your profile, and follow it. Your new profile will be in the form of either `@your_username@example.com` or `@example.com@example.com`, so that is what you’ll search for.
+1. On your blog, publish a new post.
+1. From Mastodon, check to see if the new post appears in your Home feed.
+
+Please note that it may take up to 15 minutes or so for the new post to show up in your federated feed. This is because the messages are sent to the federated platforms using a delayed cron. This avoids breaking the publishing process for those cases where users might have lots of followers. So please don’t assume that just because you didn’t see it show up right away that something is broken. Give it some time. In most cases, it will show up within a few minutes, and you’ll know everything is working as expected.
+
+== Frequently Asked Questions ==
+
+= tl;dr =
+
+This plugin connects your WordPress blog to popular social platforms like Mastodon, making your posts more accessible to a wider audience. Once installed, your blog can be followed by users on these platforms, allowing them to receive your new posts in their feeds.
+
+= What is the status of this plugin? =
+
+Implemented:
+
+* blog profile pages (JSON representation)
+* author profile pages (JSON representation)
+* custom links
+* functional inbox/outbox
+* follow (accept follows)
+* share posts
+* receive comments/reactions
+* signature verification
+
+To implement:
+
+* threaded comments support
+* replace shortcodes with blocks for layout
+
+= What is "ActivityPub for WordPress" =
+
+*ActivityPub for WordPress* extends WordPress with some Fediverse features, but it does not compete with platforms like Friendica or Mastodon. If you want to run a **decentralized social network**, please use [Mastodon](https://joinmastodon.org/) or [GNU social](https://gnusocial.network/).
+
+= What if you are running your blog in a subdirectory? =
+
+In order for webfinger to work, it must be mapped to the root directory of the URL on which your blog resides.
+
+**Apache**
+
+Add the following to the .htaccess file in the root directory:
+
+	RedirectMatch "^\/\.well-known/(webfinger|nodeinfo|x-nodeinfo2)(.*)$" /blog/.well-known/$1$2
+
+Where 'blog' is the path to the subdirectory at which your blog resides.
+
+**Nginx**
+
+Add the following to the site.conf in sites-available:
+
+	location ~* /.well-known {
+		allow all;
+		try_files $uri $uri/ /blog/?$args;
+	}
+
+Where 'blog' is the path to the subdirectory at which your blog resides.

+
+Follow the normal instructions for [installing WordPress plugins](https://wordpress.org/support/article/managing-plugins/).
+
+= Automatic Plugin Installation =
+
+To add a WordPress Plugin using the [built-in plugin installer](https://codex.wordpress.org/Administration_Screens#Add_New_Plugins):
+
+1. Go to [Plugins](https://codex.wordpress.org/Administration_Screens#Plugins) > [Add New](https://codex.wordpress.org/Plugins_Add_New_Screen).
+1. Type "`activitypub`" into the **Search Plugins** box.
+1. Find the WordPress Plugin you wish to install.
+    1. Click **Details** for more information about the Plugin and instructions you may wish to print or save to help setup the Plugin.

+1. The resulting installation screen will list the installation as successful or note any problems during the install.
+1. If successful, click **Activate Plugin** to activate it, or **Return to Plugin Installer** for further actions.
+
+= Manual Plugin Installation =
+
+There are a few cases when manually installing a WordPress Plugin is appropriate.
+
+* If you wish to control the placement and the process of installing a WordPress Plugin.
+* If your server does not permit automatic installation of a WordPress Plugin.
+* If you want to try the [latest development version](https://github.com/pfefferle/wordpress-activitypub).
+
+Installation of a WordPress Plugin manually requires FTP familiarity and the awareness that you may put your site at risk if you install a WordPress Plugin incompatible with the current version or from an unreliable source.
+
+Backup your site completely before proceeding.
+
+To install a WordPress Plugin manually:
+
+* Download your WordPress Plugin to your desktop.
+    * Download from [the WordPress directory](https://wordpress.org/plugins/activitypub/)
+    * Download from [GitHub](https://github.com/pfefferle/wordpress-activitypub/releases)
+* If downloaded as a zip archive, extract the Plugin folder to your desktop.
+* With your FTP program, upload the Plugin folder to the `wp-content/plugins` folder in your WordPress directory online.
+* Go to [Plugins screen](https://codex.wordpress.org/Administration_Screens#Plugins) and find the newly uploaded Plugin in the list.
+* Click **Activate** to activate it.

+Use your existing LDAP as authentication-backend for your wordpress!

+
+So what are the differences to other Wordpress-LDAP-Authentication-Plugins?
+
+* **Flexible**: You are totaly free in which LDAP-backend to use. Due to the extensive configuration you can
+freely decide how to do the authentication of your users. It simply depends on your
+filters
+* **Independent**: As soon as a user logs in, it is added/updated to the Wordpress' user-database
+to allow wordpress to always use the correct data. You only have to administer your users once.
+* **Failsafe**: Due to the users being created in Wordpress' User-database they can
+also log in when the LDAP-backend currently is gone.
+* **Role-Aware**: You can map Wordpress' roles to values of an existing LDAP-attribute.
+
+## How does the plugin work?
+
+Well, as a matter of fact it is rather simple. The plugin verifies, that the user
+seeking authentification can bind to the LDAP using the provided password.
+
+If that is so, the user is either created or updated in the wordpress-user-database.
+This update includes the provided password (so the wordpress can authenticate users
+even without the LDAP), the users name according to the authLDAP-preferences and
+the status of the user depending on the groups-settings of the authLDAP-preferences
+
+Writing this plugin would not have been as easy as it has been, without the
+wonderfull plugin of Alistair Young from http://www.weblogs.uhi.ac.uk/sm00ay/?p=45
+
+## Configuration
+
+### Usage Settings
+
+* **Enable Authentication via LDAP** Whether you want to enable authLdap for login or not
+* **debug authLdap** When you have problems with authentication via LDAP you can enable a debugging mode here.
+* **Save entered Password** Decide whether passwords will be cached in your wordpress-installation. **Attention:** Without the cache your users will not be able to log into your site when your LDAP is down!
+
+### Server Settings
+
+* **LDAP Uri** This is the URI where your ldap-backend can be reached. More information are actually on the Configuration page
+* **Filter** This is the real McCoy! The filter you define here specifies how a user will be found. Before applying the filter a %s will be replaced with the given username. This means, when a user logs in using ‘foobar’ as username the following happens:
+
+    * **uid=%1$s** check for any LDAP-Entry that has an attribute ‘uid’ with value ‘foobar’
+    * **(&(objectclass=posixAccount)(|(uid=%1$s)(mail=%1$s)))** check for any LDAP-Entry that has an attribute ‘objectclass’ with value ‘posixAccout’ and either a UID- or a mail-attribute with value ‘foobar’
+
+    This filter is rather powerfull if used wisely.
+
+### Creating Users
+
+* **Name-Attribute** Which Attribute from the LDAP contains the Full or the First name of the user trying to log in. This defaults to name
+* **Second Name Attribute** If the above Name-Attribute only contains the First Name of the user you can here specify an Attribute that contains the second name. This field is empty by default
+* **User-ID Attribute** This field will be used as login-name for wordpress. Please give the Attribute, that is used to identify the user. This should be the same as you used in the above Filter-Option. This field defaults to uid
+* **Mail Attribute** Which Attribute holds the eMail-Address of the user? If more than one eMail-Address are stored in the LDAP, only the first given is used. This field defaults to mail
+* **Web-Attribute** If your users have a personal page (URI) stored in the LDAP, it can be provided here. This field is empty by default
+
+### User-Groups for Roles
+
+* **Group-Attribute** This is the attribute that defines the Group-ID that can be matched against the Groups defined further down This field defaults to gidNumber.
+* **Group-Filter** Here you can add the filter for selecting groups for the currentlly logged in user The Filter should contain the string %s which will be replaced by the login-name of the currently logged in
+
+
+## FAQ
+
+<dl>
+    <dt>Can I change a users password with this plugin?</dt>
+    <dd>Short Answer: <strong>No</strong>!<br>Long Answer: As the users credentials are not
+    only used for a wordpress-site when you authenticate against an LDAP but for
+    many other services also chances are great that there is a centralized place
+    where password-changes shall be made. We'll later allow inclusion of a link
+    to such a place but currently it's not available. And as password-hashing and
+    where to store it requires deeper insight into the LDAP-Server then most users
+    have and admins are willing to give, password changes are out of scope of this
+    plugin. If you know exactyl what you do, you might want to have a look at
+    <a href="https://github.com/heiglandreas/authLdap/issues/54#issuecomment-125851029">
+    issue 54</a>
+    wherer a way of adding it is described!
+    </dd>
+    <dt>Can I add a user to the LDAP when she creates a user-account on wordpress?</dt>
+    <dd>Short Answer: <strong>No</strong>!<br>Long Answer: Even though that is technically possible
+    it's not in the scope of this plugin. As creating a user in an LDAP often involves
+    an administrative process that has already been implemented in your departments
+    administration it doesn't make sense to rebuild that - in most cases highly
+    individual - process in this plugin. If you know exactly what you do, have a look at
+    <a href="https://github.com/heiglandreas/authLdap/issues/65">issue 65</a>
+    where <a href="https://github.com/wtfiwtz">wtfiwtz</a> shows how to implement that feature.

+=== authLdap ===
+Contributors: heiglandreas
+Tags: ldap, auth, authentication, active directory, AD, openLDAP, Open Directory
+Requires at least: 2.5.0
+Tested up to: 6.3.0

+
+Use your existing LDAP flexible as authentication backend for WordPress
+
+== Description ==
+
+Use your existing LDAP as authentication-backend for your wordpress!
+
+So what are the differences to other Wordpress-LDAP-Authentication-Plugins?
+
+* Flexible: You are totaly free in which LDAP-backend to use. Due to the extensive configuration you can freely decide how to do the authentication of your users. It simply depends on your filters
+* Independent: As soon as a user logs in, it is added/updated to the Wordpress' user-database to allow wordpress to always use the correct data. You only have to administer your users once.
+* Failsafe: Due to the users being created in Wordpress' User-database they can also log in when the LDAP-backend currently is gone.
+* Role-Aware: You can map Wordpress' roles to values of an existing LDAP-attribute.
+
+For more Information on the configuration have a look at https://github.com/heiglandreas/authLdap
+
+== Installation ==
+
+1. Upload the extracted folder `authLdap` to the `/wp-content/plugins/` directory
