You may need to adjust this number depending on the number of objects in the above relative root search path.
- **_Important note on `mysql-auto-create-accounts:`_** This line is optional and can be deleted. This line ensures that all Active Directory user accounts will have a matching user account created in the Guacamole db at first logon. Local Guacamole accounts are NOT necessarily needed for access to Guacamole connections - these are only necessary when deploying MFA or you want to assign other settings specific to individual users. Domain users can be provisioned access to Guacamole sessions connections without creating local users in the Guacamole db. For many use cases, manually creating a small number of Guacamole user accounts to match their domain accounts may be more preferable than all users inheriting access to establish a local account in the Guacamole db. See below for manual account setup.
+- **Important note on `mysql-auto-create-accounts:`** This line is optional and can be deleted if using Active Directory authentication without Guacamole's implementation of MFA. This line ensures that all Active Directory user accounts will have a matching user account created in the Guacamole database at thier first Guacmaole logon with thier AD accout. Only if Gucamole's MFA feature is to be provisioned is a local Guacamole account required, and automating this step can aid MFA deployment. If you want to provision Guacamole MFA access to just a limited selection of Active Diretory users, you may remove this line and manually create the passwordless Guacamole database local account pairings as needed.

 TLS task A. Adjust this line in the above template for add-ldap-auth-guacamole.sh (Values can be none, ssl or stattls) 
 ```
 ldap-encryption-method: starttls 
 ```
 TLS task B. Next, you must obtain your AD TLS cert. 
 ```

              sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'
 ```
 TLS task C. Copy the certificate contents from -----BEGIN CERTIFICATE----- to -----END CERTIFICATE----- and paste this into a file (e.g. adcert.pem as per below)
 ```
 sudo nano /etc/ssl/certs/adcert.pem  # then paste certificate output
 ```
 TLS task D. Now import the AD cert file into the Java keystore
 ```
 sudo keytool -importcert -alias adcert \

 ## 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
-<img src="https://github.githubassets.com/images/icons/emoji/rocket.png" width="35"> To start building your Guacamole appliance, paste the below link into a terminal and just follow the prompts **(no need for sudo, but the user must be a member of the sudo group)**:
+🚀 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
 ```

-<img src="https://github.githubassets.com/images/icons/emoji/wrench.png" width="35"> **The main script guides you through the installation process in the following steps:**
+🔧 **The main `1-setup.sh` script guides the installation with the following steps:**
-1. Confirm your system hostname and local DNS domain suffix. (Must be consistent for TLS proxy)
+1. Setup the system hostname & local DNS name (Local DNS must be consistent for TLS proxy).
-2. Choose a locally installed or remote MySQL instance, set database security preferences.
+2. Select either a local MySQL install or use a pre-existing local or remote MySQL instance.
-3. Pick an authentication extension: DUO, TOTP, LDAP, or none.
+3. Pick an authentication extension: DUO, TOTP, LDAP/Active Directory, or none.
 4. Select optional console features: Quick Connect & History Recorded Storage UI integrations.
-5. Decide on the Guacamole front end: Nginx reverse proxy (http or https) or keep the native Guacamole interface
+5. Select the Guacamole front end: Nginx reverse proxy (HTTP or HTTPS) or use the native Guacamole interface on port 8080.
   - If you opt to install Nginx with self-signed TLS:
     - 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.

-## Managing self signed TLS certs with Nginx (the easy way!)
+## Customising The Build
-   - **To change the reverse proxy dns name or IP:** 
+⚙️ **To customise the many available script options:**
-     - Just re-run ` 4a-install-tls-self-signed-nginx.sh`as many times as you like (accompanying server and browser client certs will also be updated) 
+
-   - **To renew certificates only, or change IP only:**
+- Exit `1-setup.sh` at the first prompt.
-     - Simply run `refresh-tls-self-signed-nginx.sh` as needed.
+- All configurable script options are shown under **Silent setup options** at the start of `1-setup.sh`. 
-   - **Above scripts will also:**
+- Certain combinations of the **Silent setup options** will allow for a fully unattended install supporting mass deployment or highly customised docker builds.
-     - Create and save new client browser certificates to `$HOME/guac-setup`
+- Re-run your edited script locally after making changes (do not re-run the automatic install web link - see below). 
-     - Provide on-screen instructions for client certificate import (no more pesky browser warnings and that pro look). 
+
-   
+**Other custom install notes:**
 - **Caution:** Re-running the auto-installer link re-downloads the suite of scripts which will overwrite any custom script edits. You must run 1-setup.sh LOCALLY after editing. If any child scripts are edited, their corresponding download links in 1-setup.sh script must also be commented out.
 - Upgrade scripts are **automatically customised with your specifc installation settings** for consistent future updates.
 - Nginx reverse proxy is configured to default to at least TLS 1.2. For ancient systems, see commented sections of the `/etc/nginx/nginx.conf` file after install.
 - A daily MySQL backup job is automatically configured under the script owner's crontab.
 - The Quick Connect option brings some extra security implications, be aware of potential risks in your environment.
 **Post-install manual hardening options:**
 - `add-fail2ban.sh`: Adds a lockdown policy for Guacamole to guard against brute force password attacks.
 - `add-tls-guac-daemon.sh`: Wraps internal traffic between the guac server & guac application in TLS.
 - `add-auth-ldap.sh`: Template script for simplified Active Directory integration.
 - `add-smtp-relay-o365.sh`: Template script for email alert integration with MSO65 (BYO app password).

 ## Branding The Guacamole UI Theme
 🎨 **Follow the theme and branding instructions** [here](https://github.com/itiligent/Guacamole-Install/tree/main/guac-custom-theme-builder). To revert to the default theme, simply delete the branding.jar file from `/etc/guacamole/extensions`, clear your browser cache and restart.
 ---
 ## Managing Self-Signed TLS Certs With Nginx
 **To renew self-signed certificates or change the reverse proxy local DNS name/IP address:** 
 - Re-run `4a-install-tls-self-signed-nginx.sh` to create a new Nginx certificate (new browser client certificates will also be created for re-import). Always clear your browser cache after changing certificates.

 ## Installation Instructions
 <img src="https://github.githubassets.com/images/icons/emoji/unicode/2699.png" width="35"> 
 ### **Paste and the wget autorun link, thats it! *But if* you want to make Guacamole your own and customise...**
 **Exit `1-setup.sh` at the first prompt**. All the configurable options can be found at the start of `1-setup.sh`. Certain combinations of edits will even produce an unattended install!
 **Other useful install notes:**
 - **Caution: Be aware that running the auto-run link again re-downloads the suite of scripts and will overwrite your changes. You must run setup locally after editing the setup script.** (Also be sure to comment out the download links in the setup script for any other scripts you want to edit, but there should be little need to touch these.)
 - Many of the scripts in the suite are **automatically adjusted with your chosen installation settings** to form a matched & transportable set. This allows you to add extra features after installation whilst avoiding mismatches with the original install.
 - Nginx is automatically configured to use TLS 1.2 or above (so really old browser versions may not work.)
 - A daily MySQL backup job will be automatically configured under the script owner's crontab.
 - **Security info:** The Quick Connect and History Recorded Storage options bring a few security implications; so be aware of potential risks in your particular environment.
 **For the more security minded, there's several post-install hardening script options available:**
 - `add-fail2ban.sh`: Adds a lockdown policy for Guacamole to guard against brute force attacks.
 - `add-tls-guac-daemon.sh`: Wraps internal server daemon <--> guac application traffic in TLS.
 - `add-auth-ldap.sh`: A template script for Active Directory integration.
 - `add-smtp-relay-o365.sh`: A template script for email alerts integrated with MSO65 (BYO app password).

 ## Upgrading Guacamole
-<img src="https://github.githubassets.com/images/icons/emoji/globe_with_meridians.png" width="35"> To upgrade Guacamole, edit `upgrade-guac.sh` to relfect the latest versions of Guacamole and MySQL connector/J before running it. This script will also automatically update the installed extensions.
+🌐 To upgrade Guacamole, edit `upgrade-guacamole.sh` to reflect the latest versions of Guacamole & MySQL connector/J before running. This script will automatically update TOTP, DUO, LDAP, Quick Connect, and History Recorded Storage extensions if present.

 ## High Availability Deployment
 - 👔 **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/).

 ## Enterprise Scale Out & High Availability 
 <img src="https://github.githubassets.com/images/icons/emoji/unicode/1f454.png" width="35"> For Enterprise deployments, did you know that Guacamole can be run in a load balanced farm? To achieve this, the database, application and front end components are usually **split into 2 or 3 layers.** (VLANs & firewalls between the layers helps with security too.) See [here](https://github.com/itiligent/Guacamole-Install/tree/main/guac-enterprise-build) for how to get started.
 - **For the DATABASE layer:** Find the included `install-mysql-backend-only.sh` to install a standalone instance of the Guacamole MySQL database for your backend.
 - **For the APPLICATION layer:** Simply use the main setup script to build as many application servers as you like, just use the installer to point these to the backend database, making sure to **say no to both the "Install MySQL locally" option and any Nginx install options**.
 - **For the Front end**: There are so many choices available that are already very well documented. You could even take the (portable) Nginx scripts to build a separate TLS front end layer. Be aware that [HA Proxy](https://www.haproxy.org/) generally provides far superior session affinity and persistence under load balanced conditions [when compared to Open Source Nginx](https://www.nginx.com/products/nginx/compare-models/) as only Nginx Plus subscribers get all the proper load balancing stuff!)

 ### 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
+      - `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. The "namespace:" value MUST match the namespace image path line found in `custom-theme.css`, eg.`background-image: url('app/ext/custom-namespace/images/logo.png');`
+      - `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.
