DAP and Authentication, Authorization, and Accounting Services
RADIUS attributes consist of an attribute number and attribute value pair in the DAP record. See
Security Appliance Supported RADIUS Attributes and Values for a table that lists RADIUS
attributes that the security appliance supports.
Note For RADIUS attributes, DAP defines the Attribute ID = 4096 + RADIUS ID.
For example:
The RADIUS attribute "Access Hours" has a Radius ID = 1, therefore DAP attribute value =
4096 + 1 = 4097.
The RADIUS attribute "Member Of" has a Radius ID = 146, therefore DAP attribute value =
4096 + 146 = 4242.
•LDAP and RADIUS attributes include:
– Attribute ID—Names/numbers the attribute. Maximum 64 characters.
– Value—The attribute name (LDAP) or number (RADIUS).
To enter multiple values in the Value field, use the semicolon (;) as the delimiter. For example:
eng;sale; cn=Audgen VPN,ou=USERS,o=OAG
– =/!=—Equal to/Not equal to.
•LDAP includes the Get AD Groups button. This button queries the Active Directory LDAP server
for the list of groups the user belong to (memberOf enumerations). It retrieves the AD groups using
the CLI show-ad-groups command in the background
The show ad-groups command applies only to Active Directory servers using LDAP. Use this command
to display AD groups that you can use for dynamic access policy AAA selection criteria.
The default time that the ASA waits for a response from the server is 10 seconds. You can adjust this
time using the group-search-timeout command in aaa-server host configuration mode.
Note If the Active Directory server has a large number of groups, the output of the show ad-groups command
might be truncated based on limitations to the amount of data the server can fit into a response packet.
To avoid this problem, use the filter option to reduce the number of groups reported by the server.
