About LDAP Settings Parent topic

Configure LDAP settings for user-group definition, administrator privileges, or end-user quarantine authentication.
Configure multiple and mixed type LDAP servers from the Administration → IMSVA Configuration → Connections | LDAP screen. You cannot configure more than one LDAP server from the Configuration Wizard.
If more than one LDAP server is used, IMSVA synchronizes the account information from the LDAP servers to the IMSVA local cache. The time required for synchronization between the servers depends on the number of accounts on your LDAP servers. When synchronization completes, the time and date appear in the Last Synchronized column. IMSVA automatically synchronizes the accounts daily. You can manually trigger synchronization by clicking Save & Synchronize.
Note
Note
If you configure only one LDAP server, IMSVA directly queries data from the remote LDAP server. If you have multiple LDAP servers configured, IMSVA synchronizes all data from the remote LDAP servers to the local OpenLDAP server. In this case, the LDAP settings cannot support End-User Quarantine authentication, and performance issues may occur during data synchronization when there is a large number of LDAP servers.
Therefore, Trend Micro recommends you configure no more than 5 LDAP servers. If you want to configure more than 5 LDAP servers, use unified directory services such as Global Catalog to manage queries so that IMSVA does not need to synchronize data to the local server.
If more than one LDAP server is enabled, End-User Quarantine using LDAP authentication and EUQ single sign-on cannot be enabled.
If the LDAP settings on the Administration → Connections → LDAP screen are not configured, the following LDAP related features will not work:
  • Policy → Internal Addresses → [Search for LDAP groups]
  • Policy → [any rule] → [Sender to Recipient] → [Search for LDAP user and groups]
  • Administration → End-User Quarantine → User Quarantine Access → [Select LDAP groups to enable access]
  • Administration → Admin Accounts → Add → [LDAP authentication]

Configuring POP3 Generic Services Parent topic

For a generic POP3 service, the POP3 client logs on using the USER command and specifies the actual POP3 server and optional port number along with the user's name using the UserServerSeparator character to separate the values.
Example 1: To connect user "User1" to server "Server1", and the UserServerSeparator character is "#", the client issues the following USER command:
USER User1#Server1
Example 2: To connect to port 2000 on Server1, the following command is used:
USER User1#Server1#2000
Note
Note
If you do not specify a port number, IMSVA uses the default value of 110.
The following example shows how to configure generic POP3 settings for Outlook:

Procedure

  1. Specify the POP3 server address with IMSVA scanner IP 192.168.11.147.
