NetScaler restricting user access to cloud desktops with AD
-LDAP Configuration
A Background
In the XenDesktop Cloud Desktop delivery platform, NetScaler is the most common security gateway used to deliver cloud desktops to the public network. Many times the customer's access to the Cloud Desktop public network also has a public network bandwidth and information security considerations, so you want to be able to cloud desktop public access can restrict and specify that special personnel have access.
Two Principle
When a user types credentials and presses the ENTER key on the login page of the NetScaler Gateway virtual server, NetScaler first searches for the entered user name in Active Directory (LDAP). If an LDAP search filter is not defined in LDAP policy/server, NetScaler will search all Active Directory user names to find matches. When a match is found, NetScaler extracts the user's full distinguished name (DN) and authenticates Active Directory with the user's DN and password.
If an LDAP search filter is defined, only the user name that matches the LDAP search filter is searched to find the user name match. For example, if you construct an LDAP search filter to search only members of an Active Directory group, the user name entered by the user must match the members of that group.
