 - If not using the **mysql-auto-create-accounts** directive, manually re-create the exact user account names in Guacamole as those in the directory that you wish to give specific local adminstrative permissions and/or provision Guacamole's MFA access. **DO NOT configure a Guacamole password for any users that will be exclusively authenticating via Active directory**. Guacamole database local user accounts without a password are first given an MFA challenge by the local Guacamole application (Only where the local passwordless Guacamole account is configured for MFA) and then will be brokered to Active Directory for their Kerberos authentication challenge. Guacamole database local user accounts that are given passwords in Guacamole will always refer to the local database account for authentication, never Active Directory. This design allows for a matrix of local, domain, MFA & non-MFA access use cases to be deployed.

 - As described above, logging on with the Guacamole admin user password will authenticate with the local Guacamole admin account, conversely if the Guacamole admin domain account password is given, the domain account is authenticated via Active Directory and then passed through as authorized to administer Guacamole. It may sometimes be necessary to log on with the local Guacamole admin account to manage some application functions, but be aware that when doing so you will not be able to view and search the user list from Active Directory. Only when logged on with the domain version of the Guacamole admin account can domain user permissions to various Guacamole sessions and objects be delegated and managed.

-This suite of build and management scripts makes setting up a secure Guacamole jump server a breeze. It supports TLS reverse proxy (self-signed or Let's Encrypt), Active Directory integration, multi-factor authentication, Quick Connect & History Recording Storage UI enhancements, a custom UI theme creation template (with dark mode as default), auto database backup, O365 email alerts, internal security hardening options, and a fail2ban policy for defense against brute force attacks. The suite also includes code for enterprise deployment similar to [Amazon's Guacamole Bastion Cluster](http://netcubed-ami.s3-website-us-east-1.amazonaws.com/guaws/v2.3.1/cluster/).
+## Introduction
+
+#### v1.6.0 is working. Issues and notes are tracked in https://github.com/itiligent/Easy-Guacamole-Installer/issues/78
+
+This install script automatically sets up a Guacamole jump-host with optional for TLS reverse proxy (self-signed or Let's Encrypt), Active Directory integration, multi-factor authentication, Quick Connect & History Recording Storage UI enhancements. Other options also include a custom UI dark themed template, auto database backups, email alerts and internal hardening options including fail2ban for defence against brute force attacks. There is also facility for enterprise deployment similar to [Amazon's Guacamole Bastion Cluster](http://netcubed-ami.s3-website-us-east-1.amazonaws.com/guaws/v2.3.1/cluster/).
 
 ## Automatic Installation
 
-🚀 To start building your Guacamole appliance, paste the below link into a terminal & follow the prompts (**A secure build requires you do NOT run this script as sudo or root, but the script will prompt for sudo**): 
+🚀 Move to you your home directory, paste the below link, then follow the prompts (**do NOT run as root, the script will prompt for sudo**): 
 
 ```shell
 wget https://raw.githubusercontent.com/itiligent/Guacamole-Install/main/1-setup.sh && chmod +x 1-setup.sh && ./1-setup.sh
 ```
+---
 
 ## Prerequisites
 
-🔒 **Before diving in, make sure you have:**
-
-- **A compatible OS (with sudo & wget packages installed):**
-  - **Debian: 12.x, 11.x, 10.x**
-  - **Ubuntu LTS variants: 24.04, 23.04, 22.04, 20.04**
-  - **Raspbian Buster or Bullseye**
-  - **Official vendor cloud images equivalent to the above versions.** 
-    - (if your cloud image uses an IP of 127.0.1.1, [see here to use TLS with Nginx](https://github.com/itiligent/Guacamole-Install/issues/21))
-- **1 CPU core + 2GB RAM for every 25 users (plus minimum RAM & disk space for your selected OS).**
+📋 **You will need:**
+  - **Supported OS: Debian 12 or 13** | **Ubuntu LTS 22.x or 24.x** | **Raspbian**
+  - **1 CPU core + 2GB RAM for every 25 users (plus minimum RAM & disk space for your selected OS).**
 - **Open TCP ports: 22, 80, and 443 (no other services using 80, 8080 & 443)**
-- **If selecting either of the TLS reverse proxy options, you must create an internal DNS record for the internal proxy site, and an additional public DNS record if selecting the Let's Encrypt option.**
-- **Sudo package installed**
-- **The username running the 1-setup.sh script must have sudo permissions**
+- **For both TLS reverse proxy options you will need a PRIVATE DNS record for the internal proxy site, and an additional PUBLIC DNS record for the Let's Encrypt option.**
+- **Sudo & wget packages installed**
+- **The user running `1-setup.sh` must have sudo permissions.**

+     - New server & client browser certificates are saved to `$HOME/guac-setup/tls-certs/[date-time]/`.
      - Optionally follow on-screen instructions for client certificate import to avoid https browser warnings.
 
-## Custom Installation Instructions
+---
 
-⚙️ **If you want to customize the available script options:**
+## Customising The Build

 ## High Availability Deployment
 
-👔 **Did you know that Guacamole can run in a load-balanced high availability farm with layered physical/virtual separation between front end, application, and database layers?**
+- 👔 **For a separate DATABASE layer:** Use the `install-mysql-backend-only.sh` [here](https://github.com/itiligent/Guacamole-Install/tree/main/guac-enterprise-build) to install a standalone instance of the Guacamole MySQL database.
+- 👔 **For a separate APPLICATION layer:** Run `1-setup.sh` and point new installations to your separate database instance. Just say **no** to the "Install MySQL locally" option and any other local reverse proxy install options.
+- 👔 **For a separate FRONT END layer:** Use the included Nginx installer scripts to build out a separate Nginx front end layer, and then apply your preferred TLS load balancing technique. Alternatively, AWS/Azure/GCP load balancers or [HA Proxy](https://www.haproxy.org/) may provide superior session persistence & affinity compared to [Open Source Nginx](https://www.nginx.com/products/nginx/compare-models/).

+
+
+### How to build all Guacamole client extensions:
+Licensing prevents some extensions being supplied in binary form, therefore these must be built from source. To achieve this, follow the exact order below on a fresh Linux system **WITHOUT JVM INSTALLED**. 
+
+#### 1. Obtain the specific JDK dependency
+Download jdk-8u411-linux-x64.tar.gz from [Oracle](https://www.oracle.com/java/technologies/javase/javase8u211-later-archive-downloads.html) (needs an Oracle sign in, select the Linux x64 compressed archive and copy it to your Linux home dir) A backup of this file is achived [here]( https://1drv.ms/u/s!Asccp3ag4RnQj-dAGYyfqwf-Rf5mTg?e=uRy1DM).
+
+### 2. Install the JDK
+```
+sudo mkdir -p /usr/lib/jvm
+sudo tar zxvf jdk-8u411-linux-x64.tar.gz -C /usr/lib/jvm
+sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_411/bin/java" 1
+sudo update-alternatives --set java /usr/lib/jvm/jdk1.8.0_411/bin/java
+```
+### 3. Clone Guacamole client source
+```sudo apt update && sudo apt -y install git
+git clone https://github.com/apache/guacamole-client.git
+cd guacamole-client
+git checkout 1.5.5 # or whatever version
+```
+### 4. Install Maven and build all the client binaries (with Radius support)
+```
+sudo apt -y install maven
+mvn clean package -Plgpl-extensions
+```
+Build output should show:
+```

+### 5 Move your new extension to the Guacamole server  
+1. As sudo, copy the new `extension.jar` file (found in `guacamole-client/extensions/guacamole-auth-radius/target/`) to `/etc/guacamole/extensions` on your Guacamole server.
+2. Adjust permissions on the new `extension.jar` file with `sudo chmod 664 /etc/guacamole/extensions/extension.jar`
+3. Restart and continue configuring the new extension as per the Guacmole official documentation [here](https://guacamole.apache.org/doc/gug/).

 ## Theme customisation hints: ##
   - Do not change any of the theme's directory structure or file names. File contents can be carefully edited according to the following constraints:
-      - `MANIFEST.MF`: All values in here can be updated. Be aware that the "Name:" value MUST use same value in front of the the .jar creation command shown above in the 1st line e.g. `Name: branding` expects branding.jar
-      - `guac-manifest.json`: The "name:" value in here can be changed to anything. The "namespace:" value given in this file MUST match the namespace image path line found in `custom-theme.css`, eg.`background-image: url('app/ext/custom-namespace/images/logo.png');`
+      - `META-INF/MANIFEST.MF`: All values in here can be updated, **BUT** be aware that `Name: branding` is linked to the commands above e.g. `Name: branding` expects `branding.jar` as the .jar filename
+      - `guac-manifest.json`: The "name:" value in here can be changed to anything **BUT** the `"namespace" : "custom-namespace"` value MUST match the namespace image path line found in `custom-theme.css`, eg:
+```
+.login-ui .login-dialog .logo {
+    background-image: url('app/ext/custom-namespace/images/logo.png');
+    width: 7em;
+    height:	7em;
+    -webkit-background-size: 7em auto;
+
+}
+```
   - It is preferable to give css a range of logo sizes as shown in the template. The "smallIcon" value in `guac-manifest.json` is used for browser tab favicons. As such this file can be kept to < 80x80 pixels. The example used is 64x64 pixels.
   - Within `custom-theme.css`, you may need to experiment with the the height and width values under `.login-ui .login-dialog .logo` to scale your particular logo neatly within the dialog box. Another option is to make the login dialog box larger. Under `.login-ui .login-dialog`, experiment with adding a `max-width: 4in;` or similar. There's a ton of css options available and this template is just starting point, Google is your friend!
   - An easy way to debug and preview potential style changes is to tweak various values by setting your browser to developer mode.
