The first time you logged in to Plauti Server, you created a Connection, as described in Getting Started with Plauti Server. When you want to log in to Plauti Server again, use the same login as you used the first time, so that you are recognized as an existing member of the Team. Once logged in, you can connect to other Salesforce Orgs and Microsoft Dynamics Environments.

To log into Plauti Server again, using Salesforce login:

1. Access the server where Plauti Server is installed.
2. Open the local host login page url for Plauti Server, for example http://localhost:8881/login .
3. Click the "Salesforce Sign-in" button.
4. Click on the resultant URL, or copy the URL with the authentication code and paste it in a browser network where Salesforce is compatible.
5. Authenticate the code, and click the Allow and Confirmation buttons until Salesforce is successfully logged in.
6. Return to the local host login page for Plauti Server.

If at step 6. you keep encountering an error message, check that you are using the 18-character Salesforce Org ID, not the 15-character Org ID.

1. In the Plauti Server installation folder (plauti-server), find the env.properties file. 
2. In the env.properties file, at SF_ORGANIZATION_ID, make sure an 18-character Salesforce Org ID is entered (not 15-character).
