How-To: Deploy ModusGate with Groupwise


Product: ModusGate

Version & Build: 4.1.361+


ModusGate - Groupwise Deployment Guide

Groupwise 6.x Configuration:
The recommended configuration for ModusGate/Groupwise is to use SMTP Authentication for the auto-create mailbox mechanism and to accept logins in the form of  Groupwise v6.x supports SMTP Auth by default and does not require special configuration.
SMTP Authentication:
This method provides support for ModusGate's forward lookup feature: all incoming messages are be verified against the GWIA to ensure that the email addresses exist on your mail server.  In the Console, go to Connections - Properties - General to configure this feature.
Please consult the attached Exchange Deployment Guide, specifically the sections ModusGate Connection Creation and Other ways to configure mailbox lookup and authentication for configuration details:
  • Select SMTP_VRFY for Automatically populate user list 
  • Select SMTP_AUTH for Authentication requests
If the GWIA cannot support logins, enable Strip domain name for Authentication requests for the WebQuarantine logins.
LDAP Authentication Method:
If you are using Novell's LDAP, ModusGate can be configured to connect to it for mailbox authentication.  However, the LDAP server must be manually configured to accept plain text logins and nicknames (if required):
Groupwise Server Configuration:
  • Open the LDAP Group tab in the ConsoleOne User Management Snapin
  • Remove the checkmark for Require TLS for simple binds
  • Unload and Reload the NLDAP module on the Novell Server
  • In LDAP, manually add Groupwise Nicknames as a mail attribute for users in order for them to receive mail at their Groupwise nicknames
    • On your ModusGate server, you are pointing to your GroupWise GWIA server for LDAP authentication.  Find that GroupWise server in ConsoleOne.   In that OU, find the object LDAP Group - servername.  Open the object and go to Attribute Mappings.  Click on Add.  From the NDS Attribute drop-down section, find nickName.  Then, in the Primary LDAP attribute field, type in (case sensitive) nickName and click on OK (you may enter a description).  Click on OK on the LDAP Group page.  There is no need to reboot the server. 
    • Once the nicknames are set up, you can send email to them with the format of
Please see the attached Groupwise Sreen Capture document for more details.
ModusGate server configuration:
  • Select OpenLDAP for Automatically populate user list
  • Select SMTP_AUTH for Authentication requests
1 Note that the recommended configuration for Auto-create mailboxes has changed: select OpenLDAP from the drop-down menu, enter the required LDAP connection information (using the attached Guide as an example) and stop/restart the SMTPRS service.  (We had suggested using the Exchange 2000+ setting in version 4.0, but now that connection can ONLY be used with an Exchange server.)
SMTP Method (No Authentication):
If end users have nicknames or aliases and you do not use LDAP or are unable to manually configure the LDAP server for nicknames, you must use a simple SMTP connection for Automatically populate user list. 
WARNING: This option does not provide a forward lookup verification: messages to both valid and invalid addresses will be sent through to Groupwise and invalid mail will have to be handled internally by the GWIA. 

Configuration with Older Groupwise Versions (pre-6.x)
Older Groupwise versions do no support SMTP Auth.  If you use an LDAP server, please use the instructions above.  Otherwise, you must select SMTP for the Automatically populate user list section.  If the GWIA supports POP3 access, you may select POP3 in the Authentication requests section.
