While using SAML SSO to login to the system, the SAML response can be interpreted to change the default behavior to make the user login to a specific company/partner in a specific role. Adeptia Connect allows you to do this by implementing a custom class to read and authenticate the user information. You need to define a new Java class and place that in customClasses folder.

This option provides option lets you:

Ability to provide Provide a specific company/partner and also a specific role for logged in user
Ability to provide Provide a redirect URL to which user will be redirected after successful login
Ability to access Access custom attributes and relay state information present in SAML Response

Follow the steps below to create the custom class:

Create a new Java class to that implement the below interface.

Info
This interface provides the ability to define a custom implementation for providing the authenticated user information.

}

Compile the above class and place it customClasses folder.
Go to …<ConnectServerInstallFolder>\AdeptiaServer\ServerKernel\etc location.
1. Open applicationConfig.xml file.
2. Search for bean id 'samlSSOAuthenticationUserDetails' in the xml file.
3. Update the class value with your own custom class Name.
Info
Restart the Adeptia services to bring the changes into effect.
