| Option | Description |
|---|---|
| UAG Name | Unique Unified Access Gateway appliance name. Note: The appliance name can consist of a text string of up to 24 characters, which includes alphabets (A-Z), digits (0-9), minus sign (-), and period (.). However, the appliance name cannot have spaces. |
| Locale | Specifies the locale to use when generating error messages.en_US for American English. This is the default.ja_JP for Japanesefr_FR for Frenchde_DE for Germanzh_CN for Simplified Chinesezh_TW for Traditional Chineseko_KR for Koreanes for Spanishpt_BR for Brazilian Portugueseen_GB for British English |
| Cookies to be Cached | The set of cookies that Unified Access Gateway caches. The default is none. |
| Session Timeout | Default value is 36000000 milliseconds. Note: The value of Session Timeout on the Unified Access Gateway must be the same as the value of the Forcibly disconnect users setting on the Horizon Connection Server. The Forcibly Disconnect Users setting is one of the General Global Settings in the Horizon console. For more information about this setting, see Configuring Settings for Client and Console Sessions. |
| Quiesce Mode | Turn on this toggle to pause the Unified Access Gateway appliance to achieve a consistent state to perform maintenance tasks. |
| Monitor Interval | The interval in which Unified Access Gateway statistics are collected periodically. The minimum and maximum values range between 10 to 9999. The default value is 60. |
| SAML Signature Certificate Rollover Support | Turn on this toggle to generate SAML SP metadata with a signature certificate. Signature certificate-based entity_ID supports smooth certificate rollover with separate SP configuration on IDP. To change this value, you must reconfigure the IDP. |
| SAML Encryption Certificate Rollover Support | Turn on this toggle to generate SAML SP metadata with encryption certificate and signature certificate. Using both the certificates to compute entity_ID supports smooth certificate rollover with separate SP configuration on IDP. To change this value, download the SP metadata from Horizon Settings and configure on IDP. If enabled, IDP needs to be reconfigured when Encryption and/TLS certificate is updated in UAG. |
| Password Age | Number of days the password is valid for the user in the ADMIN role. The default value is 90 days. Maximum value that can be configured is 999 days. For password to never expire, specify the value of this field as 0. |
| Monitoring Users Password Age | Number of days the password is valid for the users in the MONITORING role. The default value is 90 days. The maximum value that can be configured is 999 days. For the password to never expire, specify the value of this field as 0. |
| Request Timeout | Indicates the maximum time Unified Access Gateway waits for a request to be received. The default value is 3000. This timeout must be specified in milliseconds. |
| Body Receive Timeout | Indicates the maximum time Unified Access Gateway waits for a request body to be received. The default is 5000. This timeout must be specified in milliseconds. |
| Maximum Connections per Session | Maximum number of TCP connections allowed per TLS session. The default value is 16. For no limit on the allowed number of TCP connections, set the value of this field to 0.Note: Field value of 8 or lower cause errors in the Horizon Client. |
| Unrecognized Request Monitoring | Turn on this toggle to monitor unrecognized requests within a rolling window of 60 minutes. The count is then shared with the broker. |
| Client Connection Idle Timeout | Specify the time (in seconds) a client connection can stay idle before the connection is closed. The default value is 360 seconds (6 minutes). A value of Zero indicates that there is no idle timeout. |
| Authentication Timeout | The maximum wait time in milliseconds before which authentication must happen. The default is 300000. If 0 is specified, it indicates no time limit for authentication. |
| Clock Skew Tolerance | Enter the permitted time difference in seconds between a Unified Access Gateway clock and the other clocks on the same network. The default is 600 seconds. |
| Max Allowed System CPU | Indicates the maximum allowed average system CPU usage in one minute. When the configured CPU limit is exceeded, new sessions are not allowed and the client receives an HTTP 503 error to indicate that the Unified Access Gateway appliance is temporarily overloaded. Additionally, the exceeded limit also allows a load balancer to mark the Unified Access Gateway appliance down so that new requests can be directed to other Unified Access Gateway appliances. Value is in percentage. Default value is 100%. |
| Join CEIP | If this toggle is turned on, the Customer Experience Improvement Program ("CEIP") information is sent to Omnissa. |
| Admin Disclaimer Text | Enter the disclaimer text based on your organization's user agreement policy. For an administrator to successfully log into the Unified Access Gateway Admin UI, the administrator must accept the agreement policy. The disclaimer text can be configured either through PowerShell deployment or by using the Unified Access Gateway Admin UI. For more information about the PowerShell setting in the INI file, see Run PowerShell script to deploy. While using the Unified Access Gateway Admin UI to configure this text box, the administrator must first log into the Admin UI and then configure the disclaimer text. On subsequent administrator logins, the text is displayed for the administrator to accept before accessing the login page. |
| DNS | Enter Domain Name System addresses that are added to /run/systemd/resolve/resolv.conf configuration file. It must contain a valid DNS search address. Click '+' to add a new DNS address. |
| DNS Search | Enter Domain Name System search that is added to /run/systemd/resolve/resolv.conf configuration file. It must contain a valid DNS search address. Click '+' to add a new DNS search entry. |
| Time Sync With Host | Turn on this toggle to synchronize the time on the Unified Access Gateway appliance with the time of the ESXi host. By default, this toggle is turned off. This option uses Open VM Tools for time synchronization and is supported only when Unified Access Gateway is deployed on the ESXi host. If you choose this option for time synchronization, then the NTP Servers and FallBack NTP Servers options are disabled. This option can be configured through PowerShell by adding the hostClockSyncEnabled parameter in the INI file. See Run PowerShell script to deploy. |
| NTP Servers | NTP servers for network time protocol synchronization. You can enter valid IP addresses and hostnames. Any per-interface NTP servers obtained from systemd-networkd.service configuration or through DHCP will take precedence over these configurations. Click '+' to add a new NTP server. If you choose this option for time synchronization, then the Time Sync With Host is disabled. |
| FallBack NTP Servers | Fallback NTP servers for network time protocol synchronization. If NTP server information is not found, these fallback NTP server host names or IP addresses will be used. Click '+' to add a new fallback NTP server. If you choose this option for time synchronization, then the Time Sync With Host is disabled. |
| Extended Server Certificate Validation | Turn on this toggle to ensure that Unified Access Gateway performs extended validation on the received SSL server certificate for outbound TLS connections to the backend servers. The extended checks include validating the expiry of the certificate, mismatches in the hostname, certificate revocation status, and extended key usage values. By default, this option is disabled. Notes: - When both OCSP and CRL URLs are present, Unified Access Gateway checks OCSP first and falls back to CRL validation only if the OCSP check is inconclusive. A valid OCSP response indicating REVOKED does not trigger CRL validation. - When CRL validation is performed, Unified Access Gateway accepts the CRL only if it is signed by the CA that issued the certificate being validated. Delegated CRL signers are not supported. This option can be configured through PowerShell by adding the extendedServerCertValidationEnabled parameter in the ini file. See Run PowerShell script to deploy. |
| SSH Public Keys | Upload public keys to enable root user access to Unified Access Gateway virtual machine when using the public-private key pair option. Administrators can upload multiple, unique public keys to Unified Access Gateway. This field is visible on the Admin UI only when the following SSH options are set to true during deployment: Enable SSH and Allow SSH root login using key pair. For information about these options, see Deploying to vSphere using the OVF Template Wizard. |
- Click Save.
