The In Aptify 5.5.1, Aptify recommends using Basic Authentication with SSL. This is the default setting when Aptify is installed. In Aptify 5.5.2, the default authentication method when Aptify is installed is Anonymous Authentication with SSL, but you can choose other authentication methods. See Choosing an Authentication Method in Aptify 5.5.2 for more details. |
When In Aptify 5.5.1, when deploying the Aptify site as an internal site, the site can be configured to use either Basic or Integrated Security (Windows Authentication). In this case, the website can be configured to use Integrated Security in this mode because the client will have access to the domain controller. (Note that using Integrated Security requires the domain controller to be accessible to the client browser.) Keep in mind the following when decided which authentication method to choose in an Aptify 5.5.1 implementation:
- When using Windows Authentication, constrained delegation must be configured from the web server to the database server, but it can be limited to the Kerberos protocol only. See Aptify Site and Network Delegation for information on configuring constrained delegation.
- When using Basic Authentication, the site must be secured with SSL to protect login credentials.
In Aptify 5,5,1, when deploying the Aptify site as an internal site, the site can be configured to use Anonymous Authentication (the default method or Basic or Windows Authentication if your organization requires authentication through IIS, for example when using single sign‐on). In this case, the website can be configured to use Integrated Security in this mode because the interface will have access to the domain controller. (Note that using Integrated Security requires the domain controller to be accessible to the web browser.) Keep in mind the following when decided which authentication method to choose:
- When using the default Anonymous Authentication, the site must be secured with SSL to protect login credentials.
- When using Windows Authentication, constrained delegation must be configured from the web server to the database server, but it can be limited to the Kerberos protocol only. See Aptify Site and Network Delegation for information on configuring constrained delegation.
- When using Basic Authentication, the site must be secured with SSL to protect login credentials.

When using Windows Authentication, Aptify uses impersonation to pass a user's login credentials from the web server to the database server. When the web server and database server reside on different computers on the network, a network administrator needs to enable delegation to allow the web server to pass the impersonated credentials to the database server.

In Aptify 5.5.2, when using Basic or Anonymous Authentication, setting up network delegation may not be required. |

Active Directory must be replicated after delegation is configured to propagate the changes to all domain controllers. |

In order to use Kerberos authentication securely, services on both the database server and the web server must be mapped to a SPN in Active Directory. This mapping is taken care of by default on the database server. However, by default, when installing IIS, the HTTP service is not mapped to a SPN.
Follow the steps to use the SETSPN utility to create the necessary SPNs for the Aptify web server (these steps are based on a Windows Server 2008 system):
- Log in to the domain controller using a domain administrator account.
- You can run the SETSPN from any Windows computer that supports the utility. However, note that the account that is currently logged into the location computer must be a domain administrator.
- You can run the SETSPN from any Windows computer that supports the utility. However, note that the account that is currently logged into the location computer must be a domain administrator.
- Launch a Command Prompt window.
- Run the following command, replacing WebServerName with the domain name of your web server.
SETSPN -L [WebServerName]
- Displayed is a list of registered SPNs for the web server. Verify whether or not there is a registered SPN for the HTTP service with the port that you are using for your AWA site. If there is a HTTP service entry, it should look similar to below. Note that there may be more than one entry if the web server's NetBIOS name and fully qualified domain name (FQDN) are not the same:
- HTTP/[WebServerName.your.domain][:NonDefaultPort]
- If the HTTP services uses the default port 80, the port preceded by a colon will not be displayed. Only non-default ports are appended to the SPN.
- If a registered SPN is not listed for HTTP service, you need to map a SPN for both the web server's NetBIOS and fully qualified names (per Microsoft best practices). The web server will be used as the account to run the HTTP service. If a SPN for the HTTP is displayed, go to the next step.
- Add a SPN for NETBIOS name of the web server using the following command. Replace :[NonDefaultPort] with a blank value (if using default port 80) or the port you are using for your AWA site. Replace [DOMAIN/WebServerName] with the NETBIOS name of the web server (this will be the account used to run the HTTP service).
SETSPN -A HTTP/[WebServerName][:NonDefaultPort] [DOMAIN/WebServerName or Domain User]- By default, the AWA site is installed under the Default website directory and uses the default port 80 (unless changed by an website administrator). In this case, you do not have to specify the port. You can simply add the SPN as SETSPN -A HTTP/[WebServerName] [DOMAIN\WebServerName or DomainAdmin].
- Note that even if you specify port 80, when displaying the list of SPNs, port 80 will not be appended to the SPN for the HTTP service.
- Add a SPN for fully qualified domain name (FQDN) of the web server using the following command. Replace :[NonDefaultPort] with a blank value (if using default port 80) or the port you are using for your AWA site. Replace [DOMAIN/WebServerName] with the fully qualified name of the web server (this will be the account used to run the HTTP service).
SETSPN -A HTTP/[WebServerFullyQualifiedName][:NonDefaultPort] [DOMAIN/WebServerName]
- By default, the AWA site is installed under the Default website directory and uses the default port 80 (unless changed by an website administrator). In this case, you do not have to specify the port. You can simply add the SPN as SETSPN -A HTTP/[WebServerName] [DOMAIN\WebServerName or DomainAdmin].
- Note that even if you specify port 80, when displaying the list of SPNs, port 80 will not be appended to the SPN for the HTTP service.
- Add a SPN for NETBIOS name of the web server using the following command. Replace :[NonDefaultPort] with a blank value (if using default port 80) or the port you are using for your AWA site. Replace [DOMAIN/WebServerName] with the NETBIOS name of the web server (this will be the account used to run the HTTP service).
- If a registered SPN does exist for the HTTP service; you have two options. You can update the existing SPN or remove and re-add a new SPN specifying the name of the web server as the account. Aptify recommends removing and then re-adding the SPN to ensure that duplicate SPNs are not created.
To remove the existing SPN (or SPNs if the NetBIOS name and fully qualified name are not the same and have be specified separately) use the following command(s):
SETSPN - D HTTP/[WebServerNetBIOSName][:NonDefaultPort] [DOMAIN/WebServerName or Domain Admin User]
SETSPN -D HTTP/[WebServerFullyQualifiedName][:NonDefaultPort] [DOMAIN/WebServerName or Domain Admin User]- Note that if the port of the existing SPN is the default port 80. The port will not be appended to the SPN.
SETSPN -A HTTP/[WebServerNetBIOSName][:NonDefaultPort] [DOMAIN/WebServerName]- By default, the AWA site is installed under the Default website directory and uses the default port 80 (unless changed by an website administrator). In this case, you do not have to specify the port. You can simply add the SPN as SETSPN -A HTTP/[WebServerName] [DOMAIN\WebServerName or DomainAdmin].
- Note that even if you specify port 80, when displaying the list of SPNs, port 80 will not be appended to the SPN for the HTTP service.
SETSPN -A HTTP/[WebServerFullyQualifiedName][:NonDefaultPort] [DOMAIN/WebServerName or Domain Admin User]- By default, the AWA site is installed under the Default website directory and uses the default port 80 (unless changed by an website administrator). In this case, you do not have to specify the port. You can simply add the SPN as SETSPN -A HTTP/[WebServerName] [DOMAIN\WebServerName or DomainAdmin].
- Note that even if you specify port 80, when displaying the list of SPNs, port 80 will not be appended to the SPN for the HTTP service.
- Note that if the port of the existing SPN is the default port 80. The port will not be appended to the SPN.
- After the appropriate SPNs have been added or modified, run the following command again to verify the HTTP services were added correctly to the registered list of SPNs for the web server. Replace WebServerName with the domain name of your web server.
SETSPN -L [WebServerName]Note title Note For more information about how to implement Kerberos authentication in a double-hop environment, see the resource below. Note that this webcast is for Windows 2003 Server, however, the principals are the same for Windows 2008 and Windows 7.
