How to configure single-sign on for Trello

ADSelfService Plus supports Active Directory (AD)-based single sign-on (SSO) for Trello and many other SAML-enabled applications. When SSO is enabled for Trello, users only have to login once into ADSelfService Plus - the identity provider. After logging in, users can securely access their Trello account without having to enter their username and password again.

ADSelfService Plus supports both Identity Provider (IdP) and Service Provider (SP)-initiated SSO for Trello.

IdP-initiated SSO for Trello: Users need to log in to the ADSelfService Plus self-service portal first, and then click on the Trello icon on the Applications dashboard to access Trello.

SP-initiated SSO for Trello: When users access Trello via a URL or bookmark, they are routed to the login page of ADSelfService Plus. After they log in, they will be redirected and logged into Trello automatically.

Follow the step-by-step guide given below to configure SSO for Trello

Before you begin

Download and install ADSelfService Plus if you haven’t already.

Configuring your Active Directory domain in ADSelfService Plus

ADSelfService Plus utilises the existing AD domain credentials for authenticating users during SSO. This makes the configuration of AD domains in ADSelfService Plus necessary before enabling SSO for Trello.

By default, ADSelfService Plus will try to add all the domains that it can discover in the network. If the required domains are automatically added, skip to step 9; otherwise, follow the steps below and add the domains manually.

1. Log in to ADSelfService Plus web console using admin credentials.
2. Click the Domain Settings link located on the top-right corner of the page.
3. An Add Domain Details window will appear.
4. In the Domain Name field, enter the name of the domain you want to add.
5. In the Add Domain Controllers field, click Discover. ADSelfService Plus will try to automatically discover the domain controllers associated with the specified domain.
6. If the domain controllers are not auto-discovered automatically, enter the domain controller name in the field provided, and click Add.
7. You can leave the authentication fields empty if you're not going to use the end user self-service features of ADSelfService Plus.
8. In Add Domain Details window, click Add.

Getting the SSO/SAML Details from ADSelfService Plus
