I tried that, but since many users in our group have restrictive access
right ("umask 077", which also seems to be the default setting of Samba
which many people here are using) it is still impossible to access files
they check in under their own user id. Therefore I tried to extend the
CVS user mapping method to permit system password checking and user
mapping at the same time. Another (maybe even better) solution would be
to tell the CVS server to override the user's umask by a set of access
rights specified by the CVS administrator.
BTW: How do you cope with the huge amount of spam being delivered via
the bug-cvs mailing list? It's really annoying...
