Create an FTD Active Directory Realm Object

Use the following procedure to create an object:

Procedure

Step 1

In the left pane, click Objects > FDM Objects.

Step 2

Click , then click RA VPN Objects (ASA & FTD) > Identity Source.

Step 3

Enter an Object Name for the object.

Step 4

Select the Device Type is as FTD.

Step 5

In the first part of the wizard, select Active Directory Realm as the Identity Source Type. Click Continue.

Step 6

Configure the basic realm properties.

  • Directory Username, Directory Password - The distinguished username and password for a user with appropriate rights to the user information you want to retrieve. For AD, the user does not need elevated privileges. You can specify any user in the domain. The username must be fully qualified; for example, Administrator@example.com (not simply Administrator).

    Note

    The system generates ldap-login-dn and ldap-login-password from this information. For example, Administrator@example.com is translated as cn=administrator,cn=users,dc=example,dc=com. Note that cn=users is always part of this translation, so you must configure the user you specify here under the common name "users" folder.

  • Base Distinguished Name - The directory tree for searching or querying user and group information, that is, the common parent for users and groups. For example, cn=users,dc=example,dc=com.

  • AD Primary Domain - The fully qualified AD domain name that the device should join. For example, example.com.

Step 7

Configure the directory server properties.

  • Hostname/IP Address - The hostname or IP address of the directory server. If you use an encrypted connection to the server, you must enter the fully-qualified domain name, not the IP address.

  • Port - The port number used for communications with the server. The default is 389. Use port 636 if you select LDAPS as the encryption method.

  • Encryption - To use an encrypted connection for downloading user and group information, select the desired method,STARTTLS or LDAPS. The default is None, which means that user and group information is downloaded in clear text.

    • STARTTLS negotiates the encryption method and uses the strongest method supported by the directory server. Use port 389. This option is not supported if you use the realm for remote access VPN.

    • LDAPS requires LDAP over SSL. Use port 636.

  • Trusted CA Certificate - If you select an encryption method, upload a Certificate Authority (CA) certificate to enable a trusted connection between the system and the directory server. If you are using a certificate to authenticate, the name of the server in the certificate must match the server Hostname / IP Address. For example, if you use 10.10.10.250 as the IP address but ad.example.com in the certificate, the connection fails.

Step 8

(Optional) Use the Test button to validate the configuration.

Step 9

(Optional) Click Add another configuration to add multiple AD servers to the AD realm. The AD servers need to be duplicates of each other and support the same AD domain. Therefore, the basic realm properties such as Directory name, Directory Password, and Base Distinguished Name must be the same across all AD servers associated with that AD realm.

Step 10

Click Add.

Step 11

Review and deploy now the changes you made, or wait and deploy multiple changes at once.
