+Active Directory Setup - Tested with Windows Server 2012
+
+1) Login as an admin to PowerDNS Admin
+
+2) Go to Settings --> Authentication 
+
+3) Under Authentication, select LDAP
+
+4) Click the Radio Button for Active Directory
+
+5) Fill in the required info -
+
+* LDAP URI - ldap://ip.of.your.domain.controller:389
+* LDAP Base DN - dc=youdomain,dc=com
+* Active Directory domain - yourdomain.com
+* Basic filter - (objectCategory=person)
+  * the brackets here are **very important**
+* Username field - sAMAccountName
+* GROUP SECURITY - Status - On
+* Admin group - CN=Your_AD_Admin_Group,OU=Your_AD_OU,DC=yourdomain,DC=com
+* Operator group - CN=Your_AD_Operator_Group,OU=Your_AD_OU,DC=yourdomain,DC=com
+* User group - CN=Your_AD_User_Group,OU=Your_AD_OU,DC=yourdomain,DC=com
+
+6) Click Save
+
+7) Logout and re-login as an LDAP user from each of the above groups.
+
+If you're having problems getting the correct information for your groups, the following tool can be useful -
+
+https://docs.microsoft.com/en-us/sysinternals/downloads/adexplorer
+
+In our testing, groups with spaces in the name did not work, we had to create groups with underscores to get everything operational.

+
+- user needs to be a LOCAL user, not LDAP etc
+- user must have already logged-in
+- user needs to be added to Domain Access Control list of domain.tld - admin status (manage all) does not suffice
+- record has to exist already - unless on-demand creation is allowed
+- ipv4 address in myip field will change A record
+- ipv6 address in myip field will change AAAA record
+- use commas to separate multiple IP addresses in the myip field, mixing v4 & v6 is allowed
+
+DynDNS also works without authentication header (user:pass@) when already authenticated via session cookie from /login, even with external auth like LDAP.
+However Domain Access Control restriction still applies.

+This guide will show you how to prepare a MySQL or MariaDB database for PowerDNS-Admin.
+
+### Step-by-step instructions
+1. ivan@ubuntu:~$ `mysql -u root -p` (then enter your MySQL/MariaDB root users password)
+2. mysql> `CREATE DATABASE powerdnsadmin CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;`
+3. mysql> `GRANT ALL PRIVILEGES ON powerdnsadmin.* TO 'pdnsadminuser'@'%' IDENTIFIED BY 'p4ssw0rd';`
+4. mysql> `FLUSH PRIVILEGES;`
+5. mysql> `quit`
+
+**NOTE:**
+
+If you plan to manage large zones, you may encounter some issues while applying changes.
+This is due to PowerDNS-Admin trying to insert the entire modified zone into the column history.detail.
+
+Using MySQL/MariaDB, this column is created by default as TEXT and thus limited to 65,535 characters.
+
+_Solution_:
+
+Convert the column to MEDIUMTEXT: 
+
+* `USE powerdnsadmin;`
+* `ALTER TABLE history MODIFY detail MEDIUMTEXT;`

+***
+**WARNING**  
+This just uses the development server for testing purposes. For production environments you should probably go with a more robust solution, like [gunicorn](https://github.com/ngoduykhanh/PowerDNS-Admin/wiki/Running-PowerDNS-Admin-with-Systemd,-Gunicorn--and--Nginx) or a WSGI server. 
+***
+
+### Following example shows a systemd unit file that can run PowerDNS-Admin
+
+You shouldn't run PowerDNS-Admin as _root_, so let's start of with the user/group creation that will later run PowerDNS-Admin:
+
+Create a new group for PowerDNS-Admin:
+
+> sudo groupadd powerdnsadmin
+
+Create a user for PowerDNS-Admin:
+
+> sudo useradd --system -g powerdnsadmin powerdnsadmin
+
+_`--system` creates a user without login-shell and password, suitable for running system services._
+
+Create new systemd service file:
+
+> sudo vim /etc/systemd/system/powerdns-admin.service
+
+General example:
+```
+[Unit]
+Description=PowerDNS-Admin
+After=network.target
+
+[Service]
+Type=simple
+User=powerdnsadmin
+Group=powerdnsadmin
+ExecStart=/opt/web/powerdns-admin/flask/bin/python ./run.py
+WorkingDirectory=/opt/web/powerdns-admin
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Debian example:
+```
+[Unit]
+Description=PowerDNS-Admin
+After=network.target
+
+[Service]
+Type=simple
+User=powerdnsadmin
+Group=powerdnsadmin
+Environment=PATH=/opt/web/powerdns-admin/flask/bin
+ExecStart=/opt/web/powerdns-admin/flask/bin/python /opt/web/powerdns-admin/run.py
+WorkingDirectory=/opt/web/powerdns-admin
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+```
+Before starting the service, we need to make sure that the new user can work on the files in the PowerDNS-Admin folder:
+> chown -R powerdnsadmin:powerdnsadmin /opt/web/powerdns-admin
+
+After saving the file, we need to reload the systemd daemon:
+> sudo systemctl daemon-reload
+
+We can now try to start the service:
+> sudo systemctl start powerdns-admin
+
+If you would like to start PowerDNS-Admin automagically at startup enable the service:
+> systemctl enable powerdns-admin
+
+Should the service not be up by now, consult your syslog. Generally this will be a file permission issue, or python not finding it's modules. See the Debian unit example to see how you can use systemd in a python `virtualenv`

+On [FreeBSD](https://www.freebsd.org/), most software is installed using `pkg`. You can always build from source with the Ports system. This method uses as many binary ports as possible, and builds some python packages from source. It installs all the required runtimes in the global system (e.g., python, node, yarn) and then builds a virtual python environment in `/opt/python`. Likewise, it installs powerdns-admin in `/opt/powerdns-admin`.
+
+### Build an area to host files
+
+```bash
+mkdir -p /opt/python
+```
+
+### Install prerequisite runtimes: python, node, yarn
+
+```bash
+sudo pkg install git python3 curl node12 yarn-node12
+sudo pkg install libxml2 libxslt pkgconf py37-xmlsec py37-cffi py37-ldap
+```
+
+## Check Out Source Code
+_**Note:**_ Please adjust `/opt/powerdns-admin` to your local web application directory
+
+```bash
+git clone https://github.com/ngoduykhanh/PowerDNS-Admin.git /opt/powerdns-admin
+cd /opt/powerdns-admin
+```
+
+## Make Virtual Python Environment
+
+Make a virtual environment for python. Activate your python3 environment and install libraries. It's easier to install some python libraries as system packages, so we add the `--system-site-packages` option to pull those in.
+
+> Note: I couldn't get `python-ldap` to install correctly, and I don't need it. I commented out the `python-ldap` line in `requirements.txt` and it all built and installed correctly. If you don't intend to use LDAP authentication, you'll be fine. If you need LDAP authentication, it probably won't work.
+
+```bash
+python3 -m venv /web/python --system-site-packages
+source /web/python/bin/activate
+/web/python/bin/python3 -m pip install --upgrade pip wheel
+# this command comments out python-ldap
+perl -pi -e 's,^python-ldap,\# python-ldap,' requirements.txt 
+pip3 install -r requirements.txt
+```
+
+## Configuring PowerDNS-Admin
+
+NOTE: The default config file is located at `./powerdnsadmin/default_config.py`. If you want to load another one, please set the `FLASK_CONF` environment variable. E.g.
+```bash
+cp configs/development.py /opt/powerdns-admin/production.py
+export FLASK_CONF=/opt/powerdns-admin/production.py
+```
+
+### Update the Flask config
+
+Edit your flask python configuration. Insert values for the database server, user name, password, etc.
+
+```bash
+vim $FLASK_CONF
+```
+
+Edit the values below to something sensible
+```python
+### BASIC APP CONFIG
+SALT = '[something]'
+SECRET_KEY = '[something]'
+BIND_ADDRESS = '0.0.0.0'
+PORT = 9191
+OFFLINE_MODE = False
+
+### DATABASE CONFIG
+SQLA_DB_USER = 'pda'
+SQLA_DB_PASSWORD = 'changeme'
+SQLA_DB_HOST = '127.0.0.1'
+SQLA_DB_NAME = 'pda'
+SQLALCHEMY_TRACK_MODIFICATIONS = True
+```
+
+Be sure to uncomment one of the lines like `SQLALCHEMY_DATABASE_URI`.
+
+### Initialise the database
+
+```bash
+export FLASK_APP=powerdnsadmin/__init__.py
+flask db upgrade
+```
+
+### Build web assets
+
+```bash
+yarn install --pure-lockfile
+flask assets build
+```
+
+## Running PowerDNS-Admin
+
+Now you can run PowerDNS-Admin by command
+
+```bash
+./run.py
+```
+
+Open your web browser and go to `http://localhost:9191` to visit PowerDNS-Admin web interface. Register a user. The first user will be in the Administrator role.
+
+### Running at startup
+
+This is good for testing, but for production usage, you should use gunicorn or uwsgi. See [Running PowerDNS Admin with Systemd, Gunicorn and Nginx](https://github.com/ngoduykhanh/PowerDNS-Admin/wiki/Running-PowerDNS-Admin-with-Systemd,-Gunicorn--and--Nginx) for instructions.
+
+The right approach long-term is to create a startup script in `/usr/local/etc/rc.d` and enable it through `/etc/rc.conf`.

+This guide will show you how to run PowerDNS-Admin via uWSGI and nginx. This guide was written using Debian 8 with the following software versions:
+- nginx 1.6.2
+- uwsgi 2.0.7-debian
+- python 2.7.9
+
+`sudo apt-get install uwsgi uwsgi-plugin-python nginx`
+
+### Step-by-step instructions
+1. Create a uWSGI .ini in `/etc/uwsgi/apps-enabled` with the following contents, making sure to replace the chdir, pythonpath and virtualenv directories with where you've installed PowerDNS-Admin:
+ ```ini
+ [uwsgi]
+ plugins = python27
+ 
+ uid=www-data
+ gid=www-data
+ 
+ chdir = /opt/pdns-admin/PowerDNS-Admin/
+ pythonpath = /opt/pdns-admin/PowerDNS-Admin/
+ virtualenv = /opt/pdns-admin/PowerDNS-Admin/flask 
+ 
+ mount = /pdns=powerdnsadmin:create_app()
+ manage-script-name = true
+ 
+ vacuum = true
+ harakiri = 20
+ buffer-size = 32768
+ post-buffering = 8192
+ socket = /run/uwsgi/app/%n/%n.socket
+ chown-socket = www-data
+ pidfile = /run/uwsgi/app/%n/%n.pid 
+ 
+ daemonize = /var/log/uwsgi/app/%n.log
+ enable-threads
+ ```
+2. Add the following configuration to your nginx config:
+ ```nginx
+ location / { try_files $uri @pdns_admin; } 
+
+ location @pdns_admin {
+     include uwsgi_params;
+     uwsgi_pass unix:/run/uwsgi/app/pdns-admin/pdns-admin.socket;
+ }
+
+ location /pdns/static/ {
+     alias /opt/pdns-admin/PowerDNS-Admin/app/static/;
+ }
+ ```
+3. Restart nginx and uwsgi.
+4. You're done and PowerDNS-Admin will now be available via nginx.
