XFOR: Connecting Disparate GroupWise Systems over Exchange Server

ID: Q240874

The information in this article applies to:
  • Microsoft Exchange Server, version 5.5 SP3

SUMMARY

It is now possible to connect two separate GroupWise mail systems over Microsoft Exchange Server 5.5 as a backbone with the latest Microsoft Exchange Connector for Novell GroupWise (available with Exchange Server 5.5 Service Pack 3). This article describes the idea and limitations of this procedure, as well as step-by-step instructions for implementing it.


MORE INFORMATION

For general information regarding the features and configuration of the Exchange GroupWise Connector, please refer to the documentation in the Gwconn.rtf file provided with the Exchange Server 5.5 Service Pack 3 CD, or located in the Exchsrvr\Connect\Exchconn\Docs folder after installation. This article assumes that the reader has a good understanding of the Exchange Server 5.5 mail server and the Exchange GroupWise Connector.

For the purpose of this article, assume the following scenario: Two separate GroupWise mail systems and one Exchange Server site with two Exchange Server computers. The requirement is to send e-mail between all mail systems and maintain a global directory list in both mail systems spanning all users in the organization.

GroupWise domain name: GWDOM1
GroupWise post office name: GWPO1
Exchange Server foreign domain name: EXCHANGE

GroupWise domain name: GWDOM2
GroupWise post office name: GWPO2
Exchange Server foreign domain name: EXCHANGE

Exchange Server site name: EXCHSITE1
Server connected to GWDOM1: EXCHSRV1
Server connected to GWDOM2: EXCHSRV2

Directory Synchronization

The default mapping rules for the Exchange GroupWise Connector can synchronize all Exchange Server mailboxes and non-GroupWise custom recipients (CRs) with each GroupWise mail system. To be able to synchronize GroupWise CRs from GWDOM1 into GWDOM2, the mapping rules and tables need to be modified. For more information on mapping rules, please refer to the Appendix section of the GroupWise documentation.

Apply the following steps to both Exchange Server computers with Exchange GroupWise Connectors:
  1. Using Notepad, open the Mexamap.tbl file. The mapping tables are in the Dxagwise folder located under Exchsrvr\Connect\Exchconn.


  2. Add the following line to the end of the list of attributes: 


    3. 
GWISEADDR2      128 Secondary-Proxy-Addresses(gwise:)
    The resulting file should look similar to the following: 
    
DN	        256 Obj-Dist-Name
TA	        256 Target-Address
ACCOUNT          32 Assoc-NT-Account
ALIAS            64 Mail-nickname
FULLNAME        128 Display-Name
FIRSTNAME        64 Given-Name
INITIALS          5 Initials
LASTNAME         64 Surname
COMPANY          64 Company
DEPARTMENT       64 Department
TITLE            32 Title
OFFICE           64 Physical-Delivery-Office-Name
PHONE            33 Telephone-Office1
FAX              33 Telephone-Fax
MOBILEPHN        33 Telephone-Mobile 
USNCREATED       12 USN-Created
GWISEADDR       128 Proxy-Addresses(GWISE:)
GWISEADDR2      128 Secondary-Proxy-Addresses(gwise:)
  3. Open the Mapgwise.tbl file and add the following line: 


    4. 
GWISEADDR2      = "EXCHANGE." POSTOFFICE "." OBJECT
    The resulting file should look similar to the following: 
    
TA              = "GWISE:" DOMAIN "." POSTOFFICE "." OBJECT
DN              = DOMAIN "." POSTOFFICE "." OBJECT
ALIAS           = OBJECT
FULLNAME        = ISEQUAL(FIRSTNAME AND(" ", LASTNAME), "", ISEQUAL(FIRSTNAME, "", ISEQUAL(LASTNAME, "", OBJECT, LASTNAME), FIRSTNAME), TRIM(FIRSTNAME AND(" ", LASTNAME),"B"))
FIRSTNAME       = FIRSTNAME
LASTNAME        = LASTNAME  
DEPARTMENT      = DEPARTMENT
TITLE           = TITLE
PHONE           = PHONE
FAX             = FAX
GWISEADDR2      = "EXCHANGE." POSTOFFICE "." OBJECT
  4. Open the Mapmex.tbl file and change the following line 
    
GWADDR          = GWISEADDR
    to the following: 


    5. 
GWADDR          = ISEQUAL(STRIP(GWISEADDR,".","L","R"), "EXCHANGE",GWISEADDR,GWISEADDR2)
  5. Save all changes.


The Exchange GroupWise Connector controls directory synchronization (dirsync) by checking that any changes to the GroupWise system are sent only if the GroupWise object belongs to the Exchange foreign domain. This is determined by the Exchange Foreign domain name field specified in the Options tab of the connector. By default, this name is EXCHANGE.

The changes in the mapping tables will automatically generate secondary GWISE proxy addresses for all GroupWise CRs by concatenating EXCHANGE as the domain address and the GroupWise user's original GroupWise mailing address. For example, a user from GWDOM1 will have the following GWISE proxies

GWISE:GWDOM1.GWPO1.GWUSER1
gwise:EXCHANGE.GWPO1.GWUSER1
where GWDOM1.GWPO1.GWUSER1 is the primary target GWISE address and EXCHANGE.GWPO1.GWUSER1 is the secondary GWISE address. This secondary address is the GWISE proxy address that is sent over to the other GroupWise system (GWDOM2).

After you change the mapping tables, perform a full dirsync reload from GroupWise to Exchange Server on both Exchange GroupWise Connectors. Check that the GroupWise CRs now have a secondary GWISE proxy address with EXCHANGE as the domain field. Running a full dirsync reload from Exchange Server to GroupWise populates the GroupWise mail system with GroupWise users from the second GroupWise mail system.

Messaging

The default mail routing for the Exchange GroupWise Connector assumes that all mail destined for a GroupWise mail system traverses only one connector. Each GroupWise connector address space entry needs to be modified from the default GWISE:* address to a unique GWISE address. For example:

EXCHSRV1-GroupWise Connector Address Space Entry

Type: GWISE
Address: GWDOM1.*.*
Cost: 1

EXCHSRV2-GroupWise Connector Address Space Entry

Type: GWISE
Address: GWDOM2.*.*
Cost: 1

If additional GroupWise domains are present, they need to be added to the address space list.

In each GroupWise mail system, a second foreign domain representing the other GroupWise domain needs to be added. Note that current foreign domain EXCHANGE should already be in the GroupWise system. If GWDOM1 was the primary GroupWise domain, then GWDOM2 and EXCHANGE will be the two foreign domains for that GroupWise mail system. The GroupWise link configuration also needs to be modified so that this second foreign domain is linked to the API gateway.

For more information on creating a foreign domain in GroupWise and linking it to the GroupWise API gateway, please refer to the Exchange GroupWise Connector documentation (Gwconn.rtf).
