IIRC there are problems when the maximum length of a line in /etc/groups exceeds 2048 chars (think limit depends on the tool (NIS,vi,grep ...) one uses for editing this file). To get by this you could define several group names which all have the same group ID with each line length staying below the limit. This will lead to all users belonging to the same group.

group02:400:anne,doreen,emma,herriette,....
group03:400:amy,dorothea,carly,donna,....
