Creating Active Directory Profiles

Use the Create Active Directory Profile page to configure the IP address-to-user mapping information and the user-to-group mapping information to access the LDAP server.

Procedure

To create an Active Directory profile:

  1. Select Configure > User Firewall Management > Active Directory.

    The Active Directory Profile page appears.

  2. Click the + icon.
  3. Complete the configuration by using the guidelines in Table 173.
  4. Click Finish.

    A Summary page providing a preview of the complete configuration appears.

  5. Click OK to complete the configuration or Back to make any modifications.

Table 173: Fields on the Create Active Directory Profile Page

Field

Description

General Information

Name

Enter a unique string of alphanumeric characters, colons, periods, dashes, and underscores. Maximum length is 255 characters.

Description

Enter a description for the Active Directory profile; maximum length is 255 characters.

On Demand Probe

Enable the manual on-demand probing of a domain PC as an alternate method for the SRX Series device to retrieve address-to-user mapping information.

By default, the manual on-demand probing is not enabled.

Timeout

Authentication Entry Timeout

Set the timeout to 0 to avoid having the user's entry being removed from the authentication table after the timeout.

Note that when a user is no longer active, a timer is started for that user’s entry in the Active Directory authentication table. When the time is up, the user’s entry is removed from the table. Entries in the table remain active as long as there are sessions associated with the entry.

The default authentication entry timeout is thirty minutes. To disable timeout, set the interval to zero. The range is 10 through 1440 minutes.

WMI Timeout

Configure the number of seconds that the domain PC has to respond to the SRX Series device’s query through Windows Management Instrumentation (WMI) or Distributed Component Object Module (DCOM).

If no response is received from the domain PC within the wmi-timeoutinterval, the probe fails and the system either creates an invalid authentication entry or updates the existing authentication entry as invalid. If an authentication table entry already exists for the probed IP address, and no response is received from the domain PC within the wmi-timeout interval, the probe fails and that entry is deleted from the table.

The range is 3 through 120 seconds.

Filter

Filter

Set the range of IP addresses that must be monitored or not monitored.

  • Include—Specify to include IP addresses from the Available column.

  • Exclude—Specify to exclude IP addresses from the Available column.

Click Add New Address to create a new IP address and add it as either include or exclude from monitoring.

Add Domain Settings

Domain Name

Enter the name of the domain; the length of the name ranges from 1 through 64 characters. The SRX Series device can have the integrated user firewall configured in a maximum of two domains.

Example: example.net

Description

Enter a description for the LDAP server domain; maximum length is 255 characters.

Username

Enter the Active Directory account name. The range is 1 through 64 characters.

Example: administrator

Password

Enter the password of the Active Directory account. The range is 1 through 128 characters.

Example: $ABC123

Domain Controller(s)

Click the plus(+) sign to create new domain controllers.

  • Domain Controller Name— Name can range from 1 through 64 characters. A maximum of 10 domain controllers can be configured.

  • IP Address—IP address of the domain controller.

User Group Mapping(LDAP)

IP Address

Specify the IP address of the LDAP server. If no address is specified, the system uses one of the configured Active Directory domain controllers.

Example: 192.0.2.15

Port

Specify the port number of the LDAP server. If no port number is specified, the system uses port 389 for plaintext or port 636 for encrypted text.

Base DN

Enter the LDAP base distinguished name (DN).

Example: DC=example,DC=net

Username

Enter the username of the LDAP account. If no username is specified, the system will use the configured domain controller’s username.

Example: administrator

Password

Enter the password for the account. If no password is specified, the system uses the configured domain controller’s password.

Example: xxxxx

Use SSL

Enable Secure Sockets Layer (SSL) to ensure secure transmission with the LDAP server. Disabled by default, then the password is sent in plaintext.

Authentication Algorithm

Specify the algorithm used while the SRX Series device communicates with the LDAP server. By default simple is selected to configure simple(plaintext) authentication mode.

IP-User Mapping

Discovery Method

Enable the method of discovering IP address-to-user mappings.

  • WMI—Windows Management Instrumentation (WMI) is the discovery method used to access the domain controller.

Event Log Scanning Interval

Enter the scanning interval at which the SRX Series device scans the event log on the domain controller. The range is 5 through 60 seconds.

Initial Event Log TimeSpan

Enter the time of the earliest event log on the domain controller that the SRX Series device will initially scan. This scan applies to the initial deployment only. After WMIC and the user identification start working, the SRX Series device scans only the latest event log.

The range is 1 through 168 hours.

Assign Device

Device

Select these devices from the Available column and move them to the Selected column.

You can also search for the devices in the search field in both the Available and Selected columns. You can search these devices by entering the device name, device IP address, or device tag.
