LDAP Profile


  • The lightwe0ight directory access protocol (LDAP) is a protocol for querying and modifying data using directory services running over TCP/IP.
  • If you integrate LDAP database with Secure Email Gateway then the service can check whether a recipient is a valid.
  • If the recipient is not a valid user then the email is rejected.
  • This avoids wasting resources by filtering mail for invalid recipients. The LDAP profiles added here are available for selection in interfaces such as 'Manage Domains > Routes' and 'SMTP AUTH > SMTP Authentication Settings'.
  • Click 'SMTP' > 'LDAP/DB' > 'LDAP', to open the configuration screen.




LDAP Profile – Table of Column Descriptions

Column Header

Description

LDAP Profile Name

 The label provided for the custom LDAP policy. Each profile contains connection information and search settings to query the database.

Action



 Edit the details of a profile.



 Copy a profile so it can be used as the basis for a new profile.



 Delete the profile from the list.


From this screen administrators can:

  • Create and add a new LDAP profile
  • Edit a LDAP profile
  • Delete a LDAP profile


Create a new LDAP profile


You can create a new LDAP profile in two ways:

  • By clicking the copy LDAP profile button  beside a LDAP profile. This will open the 'New LDAP Profile' screen with all its details pre-populated for the copied profile.
  • By clicking the 'Add LDAP profile' link at the top




LDAP Profile - Table of Parameters

Parameter

Description

Profile Name

Enter the name of the new LDAP profile.

Connection type

Determines how Secure Email Gateway should connect to the LDAP server. The options available are:

  • Plain (Not encrypted)
  • TLS (Encrypted with the TLS protocol. Recommended)
  • SSL (Encrypted using the SSL protocol. Use if your systems have compatibility issues with TLS)

Host Name or IP Address

Enter the hostname or IP address of the LDAP/Active Directory. Secure Email Gateway will first check the primary server and will check the secondary server if the primary is not available.

Port

Specify the LDAP server port number. If you use 'Active Directory' then, instead of the default LDAP port 389, port 3826 must be used as Active Directory Catalog port.

Search Type

Select the type of search from the drop-down. The options available are:

  • Realtime - Checks the AD server each time for user validity
  • Cache - Checks the user validity from the system's cache memory and if not available checks the AD server.

Cache Time (minutes)

If the 'Cache' option is enabled as 'Search Type', this field becomes active. Enter the time in minutes the details of users are cached after which they are wiped out.

Anonymous Access

If this feature is enabled, the connection to LDAP server will be created anonymously so that username and password are not required.

Login DN

LDAP username to connect LDAP / Active Directory server.

Password

Enter the LDAP user password.

Enable catch-all for this profile

When this feature is enabled, if the recipient's address is value1-value2-value3@domain.com then Secure Email Gateway first checks whether this address is registered in LDAP. If it does not find it, it deletes value1 and checks the remaining value2-value3@domain.com address. If it does not find it again then it delete value2 and checks value3@domain.com

Search Base

Specify the search starting criteria to be used in LDAP tree.

Search Pattern

Determines which LDAP attributes will be searched in search base.

Test E-Mail Address

Enter the email address to test the LDAP connection.

Email host attribute name

Enter the mail host attribute name for the LDAP / Active Directory server.

Check Local DB Users Also

Checks for users in Local Data base users list as well.
