Change the Expiration Period for Service Provider Metadata
If you do not change the expiration period, View Connection Server will stop accepting SAML assertions
from the SAML authenticator, such as Access Point or a third-party identity provider, after 24 hours, and the
metadata exchange must be repeated.
Use this procedure to specify the number of days that can elapse before View Connection Server stops
accepting SAML assertions from the identity provider. This number is used when the current expiration
period ends. For example, if the current expiration period is 1 day and you specify 90 days, after 1 day
elapses, View Connection Server generates metadata with an expiration period of 90 days.
Prerequisites
See the Microsoft TechNet Web site for information on how to use the ADSI Edit utility on your Windows
operating system version.
Procedure
1 Start the ADSI Edit utility on your View Connection Server host.
2 In the console tree, select Connect to.
3 In the Select or type a Distinguished Name or Naming Context text box, type the distinguished name
DC=vdi, DC=vmware, DC=int.
4 In the Computer pane, select or type localhost:389 or the fully qualified domain name (FQDN) of the
View Connection Server host followed by port 389.
For example: localhost:389 or mycomputer.example.com:389
5 Expand the ADSI Edit tree, expand OU=Properties, select OU=Global, and double-click OU=Common
in the right pane.
6 In the Properties dialog box, edit the pae-NameValuePair attribute to add the following values
cs-samlencryptionkeyvaliditydays=number-of-days
cs-samlsigningkeyvaliditydays=number-of-days
In this example, number-of-days is the number of days that can elapse before a remote View Connection
Server stops accepting SAML assertions. After this period of time, the process of exchanging SAML
metadata must be repeated.
Using Smart Card Certificate Revocation Checking
You can prevent users who have revoked user certificates from authenticating with smart cards by
configuring certificate revocation checking. Certificates are often revoked when a user leaves an
organization, loses a smart card, or moves from one department to another.
View supports certificate revocation checking with certificate revocation lists (CRLs) and with the Online
Certificate Status Protocol (OCSP). A CRL is a list of revoked certificates published by the CA that issued the
certificates. OCSP is a certificate validation protocol that is used to get the revocation status of an X.509
certificate.
You can configure certificate revocation checking on a View Connection Server instance or on a security
server. When a View Connection Server instance is paired with a security server, you configure certificate
revocation checking on the security server. The CA must be accessible from the View Connection Server or
security server host.
You can configure both CRL and OCSP on the same View Connection Server instance or security server.
When you configure both types of certificate revocation checking, View attempts to use OCSP first and falls
back to CRL if OCSP fails. View does not fall back to OCSP if CRL fails.
