permission problem - cannot checkout files

[Roni Abusch]

I'm new at CVS, and I tried for the first time to start a project in it.
I've imported my sources and created a project in CVS, but for some reason,
I'm the only one that can use it. When other people are trying to checkout
this project, they get the following message:

cvs checkout: Updating Proj1
cvs checkout: failed to create lock directory for `/home/cvsroot/Proj1'
(/home/cvsroot/Proj1/#cvs.lock): Permission denied
cvs checkout: failed to obtain dir lock in repository `/home/cvsroot/Proj1'
cvs [checkout aborted]: read lock failed - giving up

Can please someone help me and tell me what did I do wrong?
