[cvsnt] limited user access

[Sven.Fondel at np-gmbh.com]

hello,

i want to set up a bunch of users with only read permissions on a
repository.
they should not be able to modify the archive with the commit command.

i could swear that i´ve seen a description around but don´t remember where.

my passwd file looks like this
the users are part of a domain calles "NP"
<<<<<<<<<<<<
klitschko:!NP
lewis:!NP
<<<<<<<<<<<<

how can i setup the user "lewis" for only read permission?

thanks in advance

Sven Fondel
