product:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problem description:
SQL1060N error returned when user tries to connect to database. 
 
The user belongs to a group that has granted connect priviledge. 
 
Problem caused by DB2 imposed a limitation of returning 64 
groups of a user when FASTGROUPS=TRUE is set.

of the user is being retrieved.
