If you encounter a javax.naming.SizeLimitExceededException when you use the , you might have encountered a maximum size limit. You can modify this limit in the portlet.xml as follows:
<portlet> <portlet-name>PortalUserGroupSelection</portlet-name> <portlet-class> com.novell.afw.portal.portlet.core.permission.PortalUserGroupSelection </portlet-class> <init-param> <name>MIN_CACHE_SIZE</name> <value>20</value> </init-param> <init-param> <name>MAX_CACHE_SIZE</name> <value>200</value> </init-param> <init-param> <name>PAC_MAX_RESULTS</name> <value>2000</value> </init-param>
Redeploy the User Application after you make this change.
