Batch creation of user accounts

[Alfred V. <alf...@up...>]

Hi,
I posted this sometime back but not sure whether a replied came forth.
I can create user accounts individually, test the mail and retrieve. But 
I can't retrieve mail with the accounts created in batch.
The accounts are created though. It seems that the settings in batch 
mode are not complied with i.e

create:username:password:userid:gid:real name:home 
dir:shell:min:max:inactive:expire

The gid for instance is not set to the gid provided but is same as 
username which isn't what I want.
Are there system wide default settings which override what I specify?

Any help appreciated.
