LDAP Server Configuration

If you don’t want to create an LDAP server through a Docker container as shown in Installation, you can manually configure one by following these steps.

Steps 3 and onward can also be used to add users to an existing database.

All these steps are inspired from this blog.

Installation:

 sudo apt-get update
 sudo apt-get upgrade -y
 sudo apt-get install slapd ldap-utils -y

During the setup, it will ask you to provide an Administrator password.

Configuration:
```
sudo dpkg-reconfigure slapd
```
It will ask you several questions for configuring SLAPD; these example values have been tested.
- Omit: No (Keeps default configuration of the ldap server)
- DNS domain name: example.com
- Organisation name: Example Organization
- Admin password: pwd (Keep same as the earlier one and confirm the same)
- Database Type: MDB
- Purging Database: Yes
- Move old Database: Yes
There is an example file in this repository named OpenLDAP_data.ldif that will create a few organizational units in your LDAP database and then add a few users. You should customize this to suit your organization. The base structure of the file is also adapted from the blog.
```
 ldapadd -x -D cn=admin,dc=example,dc=com -W -f OpenLDAP_data.ldif
```
You will be asked for the admin password here.
The OpenLDAP server should be running by now, you can check the status with the following command:
```
 sudo systemctl status slapd
```
If you need to manually restart or enable it use the following commands:
```
 sudo systemctl enable slapd
 sudo systemctl restart slapd
```
In case you need to remove OpenLDAP use the following commands taken from this blog:
```
 sudo apt-get remove --auto-remove slapd  
```
And to completely purge remove:
```
 sudo apt-get purge --auto-remove slapd
```
Now you can launch the Bag Database. If you used the example LDIF file to load users, you can log in with these credentials:
- username: ben, password: benspassword
- username: bob, password: bobspassword
