# Configuring back-channel authentication (SAML)

Depending on your browser single sign-on (SSO) use cases, the administrative console prompts you to configure authentication requirements for inbound messages, outbound messages, or both.

## About this task

See the following table for more information about the back-channel configuration (SAML) authentication requirements.

| A connection is configured with a SAML 2.0 SLO endpoint that uses the artifact binding on **Protocol Settings > SLO Service URLs**.           | Inbound                                  | Artifact resolution requestsSOAP messages |
| A connection is configured with a SAML 2.0 SLO endpoint that uses the SOAP binding on **Protocol Settings > SLO Service URLs**.               | Outbound                                 | SOAP SLO messages                         |
| The SAML 2.0 Artifact binding is enabled on **Protocol Settings > Allowable SAML Bindings**.                                                  | Outbound                                 | Outbound artifact resolution requests     |
