User-Based Attributes Policy Enforcement
You can map any standard LDAP attribute to a well-known Vendor-Specific Attribute (VSA) as well as
map one or more LDAP attribute(s) to one or more Cisco LDAP attributes.
The following example shows how to configure the ASA to enforce a simple banner for a user configured
on an AD LDAP server. On the server, use the Office field in the General tab to enter the banner text.
This field uses the attribute named physicalDeliveryOfficeName. On the ASA, create an attribute map
that maps physicalDeliveryOfficeName to the Cisco attribute Banner1. During authentication, the ASA
retrieves the value of physicalDeliveryOfficeName from the server, maps the value to the Cisco attribute
Banner1, and displays the banner to the user.
This example applies to any connection type, including the IPsec VPN client, AnyConnect SSL VPN
client, or clientless SSL VPN. In the example, User1 connects through a clientless SSL VPN connection.
To configure the attributes for a user on the AD or LDAP Server, perform the following steps:
Step 1 Right-click a user.
The Properties dialog box appears (see Figure C-3 ).
gt Operator Greater than value
eq Operator Equal to value
neq Operator Not equal to value
range Operator Inclusive range. Should be followed by two values.
