Expedition offers local user authentication and external user authentication via LDAP and Radius servers.
In this example, we will illustrate how to configure external authentication via a Windows Active Directory server.
Settings in LDAP Server
We have created a server under the domain sctc.domain.local, defined a group called "developers" and added a user "didac gil" with logon name "didacgil9".
In the figure we can notice that users authenticate with the suffix "@sctc.domain.local". We will have to take account of this value for providing the correct settings in Expedition to complete the user authentication.
Defining LDAP Server in Expedition
In Expedition, we will first define the LDAP authentication server. Only Superusers have rights for server registration or modification.
We have two different approaches for user authentication.
Approach 1. User needs to enter full logon name
Define a server providing the desired server's name, the server's address and port, server type (Windows or Linux), Search DN parameters and SSL and/or TLS usage.
In our case, we our server responds at sctc.domain.local port:389 and we have named LDAP_approach1.
The users that will use this server for authentication belong to the developers group, therefore we have provided the following Search DN: "CN=developers,DC=sctc,DC=domain,DC=local". Contact your Active Directory administrator to verify your correct Search DN parameters.
After saving, we will test the server settings clicking on the diagnostics icon. We will be required to enter an existing user's credentials.
A feedback will be provided with the results of the connection.
Through this approach, users will have to provide their full account name for authentication. In our case, firstname.lastname@example.org will be the user name account required to have a valid authentication.
Approach 2. Server specifies the user suffix
In this case, we will facilitate the user's logon, providing the suffix already in the server settings. This way, a user will only have to write their account name "didacgil9".
Notice that using this approach, all users must share the same suffix in order to be able to validate their credentials.
