Security in Vision is managed through one of two authentication strategies, either the Classic Authentication strategy or Identity Providers (IdP) strategy. Classic Authentication Strategy involves a concept known as a User Source, which is a configuration that contains multiple roles and users. IdPs allow users to authenticate against a trusted third party. Refer to Security for more information on these authentication strategies.
Selecting an Authentication Strategy
The strategy used by any given project is determined by the Authentication Strategy, found under Project Properties. See Vision Project Properties for more information.
Client Authentication Strategies
Users are given access based off of the Authentication Strategy the project is set to.
Classic Strategy
When using the classic strategy, a User Source needs to be assigned to the project. Users and roles are taken from the assigned User Source.

When utilizing this strategy, the Required Client Roles field can be used to limit access to the entire Vision Client based on a roles requirement.
Identity Provider Strategy
When using the identity provider strategy, an Identity Provider needs to be assigned to the project. Users are taken from the assigned IdP.

Vision's access control model is based on roles and security zones. Thus, the Authenticated/Roles...
and SecurityZones/...
security levels in the IdP are converted into roles and zones, respectively. As a result, IdPs need to have user attribute mapping configured for a given IdP before Vision can utilize role based access.
