# Configure custom HTTP headers

Enterprise Application Access (EAA) supports custom headers within applications. You can identify specific headers to insert and forward to the original application with these fields:

* **Header name**. Name of the header from the application.

* **Attribute**. The header type used for verification.

When you put the application behind Enterprise Application Access (EAA) an identity provider (IdP) authenticates it. Enterprise Application Access acts as a bridge between the application and IdP. Enterprise Application Access injects headers to the HTTP response to identify the application to the IdP and authenticate users.

Enterprise Application Access supports user, group, client IP, and custom. The custom attribute is an option to verify through SAML. In the SAML case, the identity provider (IdP) returns attributes to authenticate the user. The custom attribute can also accept any of the LDAP user attributes from, **System** > **Settings** > **User Attributes** for example, the `user.userPrincipalName`,`eaa.domain\samAccountName` can be sent to the application.

1. Log in to Enterprise Center.

2. In the Enterprise Center navigation menu, select **Application Access** > **Applications** > **Applications**.

3. Select your application to open it.

4. In **Advanced** enter a custom **Header name** and select **Attribute**.
   For example, add the `user.userPrincipalName` LDAP user attribute as a custom attribute in the a custom header.

5. Click **Save and Deploy**.
