#### To configure single sign-on (SSO) for a Virtual Server

1. Expand the Configurations node.
2. Select the instance to configure:
   - To configure a particular instance, expand the instance’s config node. For example, the default instance, `server`, expand the `server-config` node.
   - To configure the default settings for all instances, expand the `default-config` node.
3. Expand the HTTP Service node.
4. Expand the Virtual Servers node, and select the virtual server to be configured for single sign-on support.
5. Click Add Property.

   A blank property entry is added to the bottom of the list.

6. Enter `sso-enabled` in the Name field.
7. Enter `false` in the Value field to disable, enter `true` to enable SSO.

   SSO is enabled by default.

8. Add or change any other single sign-on properties by clicking Add Property and configuring any applicable SSO properties.

   Valid SSO properties for virtual servers are discussed in the following table.

   SSO Enabled Property Name | Description | Values
   --- | --- | ---
   `sso-max-inactive-seconds` | Number of seconds after which a user’s single sign-on record becomes eligible for purging, if no client activity is received. Access to any of the applications on the virtual server keeps the single sign-on record active. | Default is 300 seconds (5 minutes). A higher value provides longer persistence for users, but consumes more memory on the server.
   `sso-reap-interval-seconds` | Interval (in seconds) between purges of expired single sign-on records. | Default is 60.

9. Click Save.
10. Restart the Application Server if Restart Required displays in the console.
