# Setting the Primary POSIX Provider

If a tenant is connected to two external authorization providers, one of the providers is always set to be the *POSIX primary* provider. If both providers have POSIX user attributes, then in case of any conflict between POSIX attributes that are retrieved from the providers, the POSIX primary takes precedence over the other provider.

Setting the POSIX primary provider enables you to make sure that conflicting query results are resolved in favor of the provider that stores the correct POSIX attributes for users. For more information about how providers are queried, see [Overview of User Management and Authorization](/docs-5-4/docs/overview-of-user-management-and-authorization).Overview of User Management and Authorization

You can set the POSIX primary provider per tenant when you create or modify a tenant.

## Viewing the POSIX Primary Provider

To check which provider is set is the POSIX primary provider per tenant:

- In VAST Web UI, open the Tenants page (Element Store -> Tenants) and look at the Posix Primary column.
