Environment

Novell GroupWise 8 Support Pack 1
Novell Identity Manager Roles Based Provisioning Module 3.6.1

Situation

Upgrading to Groupwise 8/SP1, causes all 4 GroupWise portlets within 
Novell Identity Manager Roles Based Provisioning Module 3.6.1 to fail when attempting to access them.
 
The following exception is thrown:

[9/1/09 14:15:07:509 MDT] 00000030 SystemOut     O 14:15:07,509 ERROR

Resolution

Disabling the Apache server compression in \\SYS\apache2\conf\GWApache2.conf
will solve this problem.  The IDM GroupWise portlets appear to not handle the
compression.  The compression section is at the bottom of the file and should
look like this when commented out:

####################################################################
# This module compresses the server output before sending it
# to the client. Apache does not load this module by default.
#<IfModule !mod_deflate.c>
#    LoadModule deflate_module modules/deflate.nlm  
#</IfModule>

#<IfModule mod_deflate.c>
#    <Location /gw/>
#        SetOutputFilter DEFLATE
#        AddOutputFilterByType DEFLATE text/* application/javascript
#    </Location>
#</IfModule>
####################################################################

A restart of Apache will be necessary after this modification.
